Buying a Used Car: The Basics | Car Buying Advice

New to the world of used cars? This guide walks you through the essential steps to help you feel confident and avoid common mistakes.

💡 Quick Guide: If you're new to car buying, focus on setting a realistic budget, researching reliable models, getting a vehicle history check, and arranging a pre-purchase inspection.

Why Buy Used?

Save 20–50% vs buying new – A new car loses 15-35% of its value in the first year alone.
Less depreciation – Used cars have already taken their biggest depreciation hit, so you'll lose less money over time.
Wider choice of spec/models for your budget – Your money goes further, letting you get a higher-spec or premium model.

What to Expect

No brand-new warranties – Unless sold by a main dealer, most used cars have limited or no warranty coverage.
More to inspect/check before buying – Used cars need thorough checking for hidden issues and past damage.
Maintenance might be due sooner – Be prepared for servicing, MOT, and potential repairs in the near future.

The Buying Process (Overview)

Set a budget – Include purchase price, insurance, tax, and potential repairs. See our budget guide for details.
Research the right models – Consider your needs (space, fuel economy, reliability) and shortlist suitable cars.
Choose where to buy – Dealers offer more protection but higher prices; private sellers are cheaper but riskier. Learn more in our dealer vs private guide.
Run checks – Always get a vehicle history check (HPI) and consider a pre-purchase inspection for peace of mind.
Test drive and ask questions – Drive on different roads, check all features work, and ask about service history.
Final paperwork and payment – Ensure you get the V5C logbook, service history, and two keys if possible.

Essential Checks Before Buying

Vehicle history check – Reveals write-offs, outstanding finance, mileage discrepancies (£20 well spent).
MOT history – Check online using the registration number to spot recurring issues.
Service history – Full service history (FSH) is ideal; partial is acceptable if recent.
Visual inspection – Look for rust, panel gaps, tire wear, fluid leaks, and interior condition.
Test drive – Check for smooth acceleration, braking, steering, and listen for unusual noises.

⚠️ Watch Out: Be wary of sellers who won't let you see the car cold-started, pressure you to decide quickly, or have incomplete service history. These are common red flags.

Red Flags to Watch For

Mismatched paint or uneven panel gaps (sign of accident repair)
Reluctance to let you see the car cold-started
Excessive rust, especially on structural components
Warning lights on the dashboard
Incomplete or missing service history
Unwillingness to negotiate or pressure to decide quickly
