First Car Buying Guide: What to Check Before You Buy
Your first car is one of the biggest purchases you'll make. Here's everything you need to know to avoid costly mistakes and find the right one.
Set Your Real Budget First
Your budget isn't just the purchase price. Before looking at a single car, work out what you can genuinely afford monthly:
- Insurance — this is often the biggest shock. As a new driver, expect £1,000-£2,500+ per year depending on the car and your postcode. Get quotes before you fall in love with a car
- Fuel — estimate your monthly mileage. At 500 miles per month and 45 mpg, budget around £70-£80/month
- Road tax — check the exact amount on the DVLA website for any car you're considering
- MOT and maintenance — budget £50-£80/month as a reserve for servicing, MOTs, and unexpected repairs
- Breakdown cover — £5-£12/month. Essential for a first car
If you have £5,000 to spend, your actual car budget might be £3,500-£4,000 after setting aside money for insurance and initial running costs.
Choosing the Right First Car
Ignore what looks cool and focus on what makes sense:
- Insurance group 1-15 — anything higher and your insurance will be painful. Check the insurance group before viewing
- Small engine — 1.0-1.4 litres is plenty for a first car. Lower insurance, lower fuel costs, easier to drive
- Common make and model — parts are cheap and every garage knows how to fix them
- Good safety ratings — Euro NCAP 4-5 stars. Your safety is worth more than alloy wheels
- Proven reliability — Toyota Yaris, Ford Fiesta, Volkswagen Polo, Honda Jazz, Hyundai i10/i20 are all solid choices
Where to Buy
Each option has trade-offs:
- Franchised dealer — most expensive but strongest legal protection. Good for peace of mind if you're nervous about used cars
- Independent dealer — usually cheaper than franchised. Still covered by Consumer Rights Act 2015. Check online reviews first
- Private seller — cheapest prices but minimal legal protection. “Sold as seen” is the reality. You need to do your own checks thoroughly
- Online platforms — convenient but you can't test drive first. Factor in delivery costs and check the returns policy
Essential Checks Before Viewing
Do these from your sofa before you waste time and petrol visiting a car:
- MOT history — check for mileage consistency, recurring failures, and outstanding advisories. DriveSage does this analysis automatically
- Insurance quote — get an actual quote, not an estimate. A car you can't afford to insure is a car you can't buy
- Market value — check what similar cars are selling for on Autotrader. If it's priced well below average, ask why
- Road tax cost — check on the DVLA website using the registration number
- Recall check — the DVSA has a free recall checker to see if any safety recalls are outstanding
What to Check When You View the Car
Go in daylight, take someone experienced if possible, and check:
- Exterior — look for rust (wheel arches, sills, around the windscreen), mismatched paint (accident repair), and uneven panel gaps
- Tyres — legal minimum is 1.6mm tread. Check all four tyres and the spare. Uneven wear suggests alignment or suspension issues
- Engine bay — oil should be honey-coloured on the dipstick, not black sludge. Coolant should be at the correct level with no mayonnaise-like residue (head gasket warning)
- Interior — check all electrics work: windows, locks, lights, heater, air con. These are expensive to fix
- Test drive — listen for unusual noises, check the brakes feel firm, test at different speeds. Drive over speed bumps to test the suspension
- Documents — V5C should match the seller's name and address. Check the VIN on the V5C matches the one on the car (visible through the windscreen and on a plate in the engine bay or door frame)
Negotiating the Price
Don't pay asking price without questioning it:
- Point out any MOT advisories and their estimated repair costs
- Mention any wear items that need replacing (tyres, brakes)
- Reference what similar cars are selling for — use DriveSage's AI valuation as evidence
- Be prepared to walk away. There are always more cars
A reasonable opening offer is 10-15% below asking price. Meet somewhere in the middle.
After You Buy
Once you've bought the car:
- Register as the new keeper on the V5C immediately (online or by post)
- Insure the car before driving it away
- Check the tax is paid (it doesn't transfer with the car)
- Book a service if it's due or if the history is unclear
- Change the oil if you're unsure when it was last done — it's the cheapest protection you can give an engine
