Summary

• Best for: People who prioritise convenience, have a hard-to-sell car, or want to complete everything in one transaction.
• Get your value first: Check your car's current market value before negotiating with any dealer.

Buying a new car and wondering what to do with your old one? Part-exchange seems the obvious choice - but is it actually the best option for you?

This guide breaks down the pros and cons, shows you when part-exchange makes sense, and explains the alternatives.

What Is Part-Exchange?

Part-exchange means trading in your current car as partial payment for a new one. The dealer takes your old car and reduces the price of the new car by its trade-in value.

For example:

• New car costs £20,000
• Dealer offers £5,000 for your old car
• You pay £15,000 (plus any finance)

Simple. But is that £5,000 offer actually good value?

Advantages of Part-Exchange

1. Convenience

The biggest benefit. You don't have to:

• Advertise your car
• Deal with enquiries and time-wasters
• Arrange viewings and test drives
• Handle payment securely
• Wait for a buyer

You simply hand over the keys and drive away in your new car.

2. No Gap Between Cars

Selling privately means you might sell your car before the new one arrives - or struggle to sell while the new one waits. Part-exchange avoids this timing issue.

3. Reduced Deposit

Your old car's value reduces what you need to pay upfront or finance, making the new purchase more affordable.

4. Easier Finance Arrangements

When buying on PCP or HP finance, the part-exchange value is built into the deal, simplifying paperwork.

5. No Private Sale Risks

No risk of scams, fake payments, or awkward negotiations with strangers.

Disadvantages of Part-Exchange

1. You'll Get Less Money

This is the main downside. Dealers need to make a profit when they resell your car. Expect to receive 10-20% less than you'd get selling privately.

Car Value	Private Sale	Part-Exchange	Difference
£5,000	~£5,000	~£4,000-4,500	£500-1,000
£10,000	~£10,000	~£8,000-9,000	£1,000-2,000
£20,000	~£20,000	~£16,000-18,000	£2,000-4,000

2. Less Negotiating Power

When negotiating price on your new car AND the part-exchange value simultaneously, it's harder to know if you're getting a good deal. Dealers can shuffle numbers between the two.

3. Limited Options

You can only part-exchange where you're buying from. If the best price on your new car is at Dealer A, but Dealer B offers more for your old car, you can't combine the two.

When Part-Exchange Makes Sense

Part-exchange is often the right choice if:

• Your car is hard to sell: Unusual colours, high mileage, or unpopular models can sit unsold for months privately
• You're time-poor: The convenience is worth the price difference
• The dealer makes a strong offer: Some dealers offer competitive part-exchange prices, especially if they're keen to sell you a car
• Your car needs work: Selling a car with issues privately is difficult; dealers are more accepting
• The value difference is small: On cheaper cars, the difference might only be a few hundred pounds

---

When to Sell Privately Instead

Selling privately is usually better if:

• Your car is desirable: Popular models sell quickly and for good money
• You have time: A few weeks to find the right buyer
• The value difference is significant: On a £15,000+ car, you could gain £2,000-3,000+
• You're comfortable selling: Happy to handle enquiries, viewings, and payments

Getting the Best Part-Exchange Deal

1. Know Your Car's Value First

Before talking to any dealer, check your car's value using our valuation tool. This gives you a baseline to negotiate from.

2. Get Multiple Offers

Don't accept the first offer. Visit several dealers or use online valuation services. You might be surprised how much offers vary.

3. Negotiate Separately

Try to agree the new car's price first, then negotiate the part-exchange value separately. This prevents dealers hiding discounts in the part-exchange figure.

4. Be Honest About Condition

Dealers will inspect your car before finalising. Any issues you didn't mention will reduce the offer - sometimes dramatically.

5. Time It Right

Dealers may offer more towards month-end or quarter-end when they need sales. January and March (before plate changes) can also be good times.

Common Questions

• Can I part-exchange a car with outstanding finance?
  Yes, but the finance must be settled first. The dealer can usually arrange this - the outstanding amount is deducted from your part-exchange value.
• Can I part-exchange a car without buying from the same dealer?
  Not usually. Part-exchange is tied to purchasing a replacement. Some car buying services offer similar convenience without requiring a purchase.
• Do I need an MOT for part-exchange?
  Not necessarily, but a car with MOT will be valued higher. Dealers can still accept cars without MOT but will offer less.
• Can I part-exchange a damaged car?
  Yes, but expect a significantly reduced offer. Be upfront about any damage.

Final Thoughts

Part-exchange trades money for convenience. You'll typically get less than selling privately, but you avoid the hassle, time, and risks of doing it yourself.

The key is knowing your car's true value before you start. Armed with that knowledge, you can make an informed decision and negotiate effectively.

For many people, the peace of mind is worth a few hundred pounds. For others, the extra money from a private sale is worth the effort. There's no wrong answer - just what's right for you.
