How to Find the Best Company that Buys Cars? Complete Guide

Selling a car used to be a time-consuming process, where you had to label it for sale and wait to get a call or a door to knock. Today, there are dozens of companies fighting to buy a car. You don’t even need to move from the couch. It’s done from your mobile and could get you a better price for your car. In this guide, we’ll cut through the marketing noise. We’ll compare the top UK car-buying services, expose the hidden fees nobody talks about, and help you find the best company that buys cars.

Key Takeaways: How to Find the Best Company That Buys Cars?

Selling your car safely means comparing buyers, checking recent reviews, avoiding hidden fees, getting multiple quotes, preparing your car properly and only handing it over once cleared funds are in your bank.

• The best car-buying company is the one that offers a fair, transparent price with no hidden fees.
• Always check recent reviews, not just the overall rating. Look for signs of price drops or slow payments.
• Instant buyers offer the fastest sale, while marketplaces usually deliver the highest price.
• Watch out for admin charges like collection fees, transaction fees and same-day payment costs.
• Home collection is the easiest option, but drop-off services can pay faster.
• Get at least two quotes: one from an instant buyer and one from a marketplace.
• Clean the car, gather documents and be honest about damage to avoid last-minute valuation drops.
• Never hand over the keys until the funds are fully cleared in your bank.

Key Factors to Consider When Choosing a Car-Buying Company

When you are ready to sell your car, don’t just jump to the website. Before that, you have to do your research first. Take a moment to compare companies based on these essential criteria:

1. Reputation and Reviews

Don’t just look at the overall 4.5-star rating, but look at the most recent reviews on Trustpilot or Google. Sometimes, a company might have a great overall score from 2023. But if the last 10 reviews all complain about last-minute price drops or other issues. That’s a red flag for their current service levels.

Consider how long the company has been operating and whether they show clear contact details. This shows the transparency and authenticity of the company.

2. Pricing & Valuation Transparency

Getting a fair price is obviously the top priority. But it’s just as important that the valuation process is clear and honest. Some “Instant Buyer” sites give you a generic estimate based on a showroom-perfect car. 

Others, particularly marketplaces where you upload photos first, give you a more accurate “guaranteed” price. Because the buyer has actually seen the condition of your vehicle before making an offer.

Also, check how long your quote is valid for. In the volatile 2025 used car market, a quote is typically valid for 4 to 7 days.

3. Admin Fees

Some car-buying companies charge fees for valuation, paperwork, collection or fast payment. These can cut into your final amount, so make sure you understand them.

For example, some charge transaction fees. If your car is worth over £5,000, you might pay a £74.99 transaction fee.

However, if you want your money immediately, you have to pay faster payment fees. That’s often another £24.75 to £29.75 for a “Same Day Payment” service.

While some online platforms, like Exchange My Car, charge no admin fees from you, though they charge the dealer.

4. Collection vs. Drop-off

How the company collects the car and where you deliver it will affect convenience, time and cost:

• Drop-off: Sites like WeBuyAnyCar require you to drive to one of their 500+ branches (often a pod in a supermarket car park) and arrange your own lift home. This is fast, but it requires effort.
• Home Collection: Companies like Motorway, Carwow, and Exchange My Car typically offer free home collection. A driver comes to your house, inspects the car on your driveway, and drives it away. This is far more convenient but can take longer to arrange.

5. Payment speed and security

Once you’ve handed over the keys and paperwork, you want to be sure you’ll actually get paid without delay. Instant buyers are the kings of speed. 

If you need cash for a house deposit today, a drop-off service can have money in your bank within 15 minutes. However, marketplaces generally take 24-48 hours because the buying dealer has to initiate the transfer.

The 3 Types of Car Buying Companies

Not all “sell my car” websites work the same way. Understanding the business model behind the website will tell you if you’re going to get a fast sale or a high price.

1. Instant Online Buyers

These are companies that give you a quick online quote for your car, often within minutes. The process is simple, you enter your registration number and mileage and get the instant valuation. For example, We Buy Any Car, Exchange My Car and Motorway

If you accept, they will arrange collection or ask you to drop the car off, and you get paid right away.

It is best for those who want a hassle-free and quick sale without any delay.

Pros	Cons
✅ Fast and convenient, often with home collection	❌ Quotes may drop after inspection
✅ Minimal paperwork handled by trusted buyers	❌ Price lower than private sale
✅ Quick sale without dealing with private buyers

 

2. Online Marketplace

Marketplaces connect sellers to multiple buyers, like dealers or other private sellers, through a single platform. You don’t sell to the website; you sell through them. 

You share images of your vehicle on their site, attracting potential buyers searching for that specific model. For example, Car Wow and Auto Trader.

However, it is best for maximising profit, often getting 5 to 10% more than an instant buyer would offer. 

Pros	Cons
✅ Potentially higher offers from competing buyers	❌ May need to arrange drop-off or meet buyers
✅ Transparent process, compare quotes side by side	❌ Communication can be slower than with instant buyers
✅ Often includes guides on preparing your car for sale

 

3. Online Dealerships

These are traditional car dealerships with an online presence. You can request a quote, often for part‑exchange or full sale. They buy your car primarily to add it to their own retail stock.

For example, Cinch and Cazoo.

These are best if you are buying another car. They excel at part exchange, dropping off your new car and picking up your old one in a single seamless driveway handover.

Pros	Cons
✅ Flexible with negotiation, especially if buying a car too	❌ May give lower quotes to resell at a profit
✅ Experienced with UK paperwork and finance	❌ Fewer options for damaged, high-mileage, or unusual cars
✅ Some offer fast payment and collection services

Comparison Table: 3 Types of Car-Buying Companies

Type of Buyer	How It Works	Best For
Instant Online Buyers	You enter your reg and mileage, get an instant quote, then drop off or arrange home collection. Payment is usually made the same day.	Drivers who want a quick, hassle-free sale.
Online Marketplaces	You upload photos, dealers bid on your car, and you accept the highest offer.	Getting the highest possible price through competition.
Online Dealerships	Dealerships buy your car directly, often linked to part exchange or a new car purchase.	Selling your car while buying another.

 

Step-by-Step: How to Get the Best Price Today

You can’t change your car’s mileage, but you can change how it’s presented. Follow this 4-step workflow to boost your valuation by hundreds of pounds.

1. Get a “Baseline” Instant Quote: Start by getting a quote from Exchange My Car. This gives you a guaranteed minimum price for your car. It tells you how much it is worth today.
2. Run a Marketplace Auction: Take that baseline figure and list your car on Motorway or Carwow. Upload clear photos and be honest about damage. See if the dealers bid higher than your baseline.
3. The “15-Minute” Clean: Before any inspection or photo upload, spend 15 minutes cleaning the car. A dirty car suggests a neglected engine.
4. Gather the “Value-Add” Documents: Dealers pay more for cars that are “retail ready”. Have these ready to show that you have both sets of keys, the service history book and supporting documents. 

Common Mistakes to Avoid

Here are common mistakes that you should avoid while selling a car.

• Hiding Damage in Photos: If you use a Marketplace site, don’t try to photograph the car from a “good angle” to hide a dent. It is always better to declare it upfront for a guaranteed price.
• Forgetting the Finance Settlement Letter: If you have outstanding finance (PCP/HP), the buyer needs a valid settlement letter from your lender. Request this 3 days before you plan to sell.
• Leaving It Until the End of the Month:  Car dealers often have monthly buying targets. Selling in the last week of the month can sometimes result in slightly higher bids.
• Accepting the First Offer: Never accept the first auto-generated number you see on a screen. Always compare at least one “Instant Buyer” against one “Marketplace” to see the true spread in the market.

Frequently Asked Questions
