Buying an old car or oldtimer: what to know

An old car has a charm that new ones cannot match: simple mechanics, distinctive looks and a sense of history. It can also be a bottomless pit of time and money if you buy without knowing what you are doing. This guide covers what to think about before you fall in love with a classic.

Be clear about why you want it

An old car as daily transport is a different project than a weekend car for sunny days. Daily use means more wear, more repairs and little patience for breakdowns. A weekend car can tolerate more quirks, but it still needs regular attention and dry storage. Decide honestly how you will use it.

Rust is the main enemy

Older cars were not built with modern rust protection. Corrosion can hide in sills, floors, wheel arches, door bottoms, boot floors and the structure. Surface rust is one thing; a rotten structure is another. Look carefully and ask a specialist to examine the underside on a lift. Be suspicious of fresh underseal and thick paint on a car of this age, as they may hide problems. Compare with the signs described in signs of accident repair, since old repairs are common.

Originality and condition

• Original, well-kept cars are usually valued more than heavily modified ones, though preferences differ.
• A rebuilt car is only as good as the work done. Ask for photos and invoices of the restoration.
• A "barn find" can look charming and still cost a great deal to bring back.

Parts and knowledge

Before you buy, find out how easy it is to get parts, and whether specialists, clubs or forums exist for the model. Rare parts can be costly and slow to find. A strong owners' community is a very valuable asset, because members know the common faults and good workshops. Also consider whether a normal workshop will work on it; many modern workshops are not used to carburettors, old brakes or simple mechanical systems.

Safety expectations

Old cars were designed with less crash protection and fewer safety systems. They may lack airbags, stability control, headrests or even rear seatbelts. They can also have weaker brakes by modern standards. Drive with more distance and more care, and have the brakes, steering, tyres and lights checked carefully by a workshop. Do not try to repair brakes or safety parts yourself unless you are properly trained. For general knowledge, see brake basics and wear signs.

Papers and history

Documents matter even more with old cars, because history and identity are part of the value. Check that the VIN or chassis number on the car matches the papers, see reading a VIN, and try our VIN checker where the format is supported. Older cars may have unusual number formats. Ask about previous owners, imports and restoration records. Special rules and status for older vehicles exist in many countries and differ widely, check with the competent authority about registration, inspection, insurance and any use limits.

The real cost of owning

• Purchase price, which can be low compared with the costs after.
• Restoration or repairs, which often cost more and take longer than planned.
• Storage, ideally dry and protected.
• Specialist insurance, which can be cheaper or more complicated than normal cover. See insurance types explained.
• Fuel, as old engines can be thirsty.
• Regular maintenance, including oil changes and checks that are more frequent than on modern cars.

Use the cost of ownership tool as a starting point and add a generous reserve.

Before you buy

1. Join an owners' club or forum and ask about the common problems.
2. View several cars, to learn what a good one looks like.
3. Take along an expert who knows the model, or pay a specialist to inspect it.
4. Use the buying checklist and the inspection guide.
5. Value emotions less than records.

Learn the basics

Owning an old car is more fun if you can do simple care yourself, such as checking fluids and tyres, cleaning and storing it well. Keep a record in My Garage of what you do and spend.

Enjoying it once you own it

Old cars reward patience and regular use. Drive them often enough to keep seals and moving parts healthy, warm the engine properly and avoid leaving the car standing for months. Store it dry, keep it clean, and look underneath from time to time for leaks and rust. Small problems caught early are cheap; the same problems ignored are not.

Finally, accept that an old car has a character, and with it some quirks. If that appeals to you, and you go in with your eyes open and a realistic budget, it can be one of the most satisfying purchases you make.

What to remember

• Rust and hidden structural damage are the biggest risks.
• Check parts availability and community support first.
• Safety standards are lower; drive accordingly and check brakes and tyres.
• Papers, VIN and history matter greatly.
• Budget for more than the purchase price.
