Buying an Ex-Demo Car: Pros, Cons and What to Check

Summary

• Save 10–25%: Ex-demo cars are nearly new but significantly cheaper than brand new.
• Low mileage: Most have under 5,000 miles and come with remaining manufacturer warranty.
• Check carefully: Demo cars have been driven by many people. Inspect the bodywork and run a car history check.

An ex-demo car is one that a dealership has used for test drives and display. It's registered in the dealer's name but often has very low mileage.

They offer a smart middle ground between new and used. Here's everything you need to know.

What Is an Ex-Demo Car?

Ex-demo (or demonstrator) cars sit in dealer showrooms. Customers use them for test drives. Sales staff sometimes use them as daily runners.

They're usually 3–12 months old with 1,000–5,000 miles on the clock. Because they've been registered, they count as "used" even though they're nearly new.

This registration is what creates the saving for you. The car has already taken its biggest depreciation hit.

Pros of Buying Ex-Demo

• Big savings: Expect to save 10–25% compared to the brand-new list price.
• Nearly new condition: Most are under a year old with low mileage.
• Manufacturer warranty: The remaining factory warranty still applies.
• No factory wait: The car is there, ready to drive away. No 3–6 month order wait.
• Often well-specced: Dealers tend to demo cars with popular options like sat nav, alloys, and parking sensors.
• Dealer support: You're buying from a franchised dealer with full legal protections.

Cons to Watch For

• Test drive wear: The car has been driven by many different people, sometimes roughly.
• Limited choice: You can't pick the exact colour or specification you want.
• Warranty started earlier: The warranty clock started at registration, not when you buy it.
• Possible car park damage: Showroom cars pick up door dings and scratches from other cars.
• Higher first-year insurance: Some insurers classify ex-demos differently to used cars.

What to Check on an Ex-Demo Car

Don't assume an ex-demo car is perfect just because it's nearly new. Check these things.

1. Mileage: Under 5,000 miles is normal for a demo. Over 5,000 is high and should mean a bigger discount.
2. Bodywork: Inspect for scratches, dents, and kerbed alloys. Demo cars live in busy car parks.
3. Interior: Check for stains, scuffs, and wear. Many people have sat in and driven this car.
4. Warranty remaining: Check when the warranty started. You want as many months left as possible.
5. Service record: Even a demo should have had its first service if it's over 12 months old.
6. History check: Run a car history check even on a demo. It confirms the car is clean and the mileage is correct.

How to Negotiate the Best Deal

Ex-demo cars have room for negotiation. Dealers want to move them on.

• Know the new price: Research what the same car costs brand new. This tells you the realistic discount.
• Point out any damage: Even small scratches give you leverage to negotiate a lower price.
• Ask for extras: Free floor mats, a tank of fuel, extended warranty, or free servicing are all worth asking for.
• Compare dealers: The same model may be available as an ex-demo at several dealers. Get quotes from all of them.
• End of quarter: Dealers have sales targets. Buying at the end of March, June, September, or December often gets you the best deal.
