Buying a car is a major purchase that requires careful research and planning. Whether you're browsing listings on marketplaces like CarDash, visiting dealerships, or considering private sellers, this comprehensive guide will help you navigate the process with confidence.
From understanding your consumer rights under UK law to spotting red flags and completing essential checks, we'll walk you through everything you need to know to make an informed decision and avoid costly mistakes.
5 Steps to Buying Your Car
Set Your Budget
Determine your total budget including purchase price, insurance, tax, and running costs
Key Points:
- Calculate total cost of ownership - purchase price is just the start
- Get insurance quotes before committing (costs vary significantly by model)
- Factor in road tax - electric vehicles now pay standard VED rates (from April 2025)
- Consider fuel/charging costs - check real-world MPG or EV range figures
- Budget for maintenance, MOT (£55 from April 2025), and potential repairs
- If financing, compare APR rates from your bank, credit union, and dealer finance
Research Models & Check Reviews
Identify vehicles that match your needs and verify their reliability
Key Points:
- Browse listings on marketplaces like CarDash to understand availability and pricing
- Check reliability ratings from sources like What Car?, Auto Trader, and owner forums
- Research common faults specific to the model year you're considering
- Compare insurance groups (1-50) - lower groups typically mean cheaper premiums
- For EVs: verify real-world range, charging speed, and battery warranty coverage
- Read reviews from actual owners to understand running costs and long-term ownership
Vehicle History & Documentation Checks
Essential checks before viewing or making an offer
Key Points:
- Run an HPI check or similar (Experian, AA, RAC) - checks for outstanding finance, stolen status, and write-off history
- Verify MOT history at gov.uk/check-mot-history - shows mileage records and test failures
- Check vehicle tax status at gov.uk/check-vehicle-tax
- Confirm V5C logbook matches the seller's details and address
- For newer cars, verify manufacturer warranty status and transferability
- Check service history is complete with stamps/receipts from franchised or independent garages
Inspect & Test Drive
Thoroughly examine the vehicle in person before committing
Key Points:
- Inspect bodywork in good light - look for paint mismatches, ripples, or filler (magnet test)
- Check for rust, especially wheel arches, sills, and underneath (bring a torch)
- Test all electrics: lights, indicators, air-con, heated seats, infotainment, parking sensors
- Inspect tyres for tread depth (legal minimum 1.6mm, but 3mm+ recommended), uneven wear, age codes
- Test drive on various roads - motorway, urban, and rough surfaces; listen for unusual noises
- Check engine oil level and condition; look for leaks or warning lights on the dashboard
- For diesels with DPF, ensure regular long journeys or check DPF regeneration history
- Consider an independent inspection (AA, RAC, or mobile mechanic) for peace of mind
Negotiate & Complete Purchase
Secure the best deal and ensure all legal requirements are met
Key Points:
- Research market value using CarDash, Auto Trader, and Glass's Guide for negotiation leverage
- Point out any faults discovered during inspection to negotiate price reduction
- From a dealer: You have 30 days to reject a faulty car under Consumer Rights Act 2015
- From a private seller: Less protection - 'sold as seen' applies, so inspection is critical
- Verify V5C logbook details match seller ID; seller should send V5C/2 to DVLA on sale
- Ensure you receive V5C, MOT certificate, service book, spare keys, and any warranty documentation
- Arrange insurance before collection - driving without it is illegal
- Complete payment securely - avoid large cash transactions; use bank transfer or dealer finance
Your Consumer Rights in the UK
Buying from a Dealer
- Consumer Rights Act 2015 protects you - vehicle must be of satisfactory quality
- 30-day right to reject if vehicle is faulty
- Within 6 months: dealer must prove the fault wasn't there at sale
- Up to 6 years to claim (5 in Scotland) for faults present at purchase
- Dealer finance is regulated by the FCA - you have cooling-off rights
Buying Privately
- Limited legal protection - 'sold as seen' generally applies
- Vehicle must match description given by seller (misrepresentation is illegal)
- Seller must legally own the vehicle and disclose any known faults
- No warranty or cooling-off period - inspection is your responsibility
- Still protected against clocked mileage or undisclosed finance

Used Car Benefits
