Every classic car advert is written by someone in love. The photographs are taken at golden hour, the faults are described as character, and the price is justified by an auction result from three years ago. Buying well is mostly a matter of refusing the romance until the inspection is finished.
The good news is that the process is not mysterious. Old cars fail in predictable places, paperwork matters more than shine, and the cheapest car is rarely the cheapest ownership. Here is how to look at one without getting carried away.
Decide what you want it to do
A car for Sunday morning drives, a car for a 2,000 km holiday and a car for a restoration are three different purchases. Be specific about the use case before you look at anything. A concours car is wasted on salt and gravel; a tatty driver is miserable on a long tour.
Then set two budgets: one for the purchase and one for the first eighteen months. Whatever you think the second number is, add half. Consumables alone on a forty-year-old car can run into four figures before anything has actually broken.
Where old cars actually go wrong
Structure first. Sills, floor pans, jacking points, suspension mounts, boot floors and the base of the windscreen are the places corrosion hides. A magnet and a bright torch will tell you more than any amount of polishing. Fresh underseal can conceal a great deal; prod it.
Then electrics. Old wiring becomes brittle, grounds corrode, and previous owners add alarms and stereos with domestic connectors. Electrical faults are slow and expensive to trace, and they are the most common reason a promising project stalls.
The inspection list
- Cold start. Insist the engine is cold when you arrive. A pre-warmed engine can hide poor compression, smoke and idle faults.
- Panel gaps and paint thickness. Uneven gaps suggest accident repair; a cheap gauge will find filler under fresh paint.
- Jack it up. Grab each wheel at twelve and six, then three and nine. Play means bearings or suspension work.
- Look for originality. Matching numbers and correct trim are worth more than a long list of modifications.
- Check the paperwork. Service history, old MOT or inspection records, receipts, and a clear title. A folder of invoices is worth more than a shiny engine bay.
The parts question
Before you buy any model, price a clutch, a radiator, a set of brake discs and a windscreen. If those four items are hard to find or frighteningly expensive, the car will be too. Community knowledge is invaluable here: owners clubs know which specialists are good, which pattern parts fit, and which upgrades are actually improvements.
For market context and insurance advice, Hagerty publishes a deep archive of classic car buying guides and valuation data. Read the guides for your shortlist before you view a car, not afterwards.
Buy the best body you can find. Engines and interiors can be rebuilt. Rust is a negotiation with the whole car.
The deal
Walk away once, on purpose. If the seller will not let a specialist inspect the car, or will not let you start it cold, that is the answer. A good car will still be there tomorrow. A bad one will follow you home for years.
If the car will be used through the colder months, plan for it properly. Our guide to winter driving covers tyres, preparation and the parts of an older car that suffer most in salt and slush.
Finally, buy for the driving, not the investment. Values move. A car you use every dry weekend pays you back in a currency no auction result can match.
