Peugeot 403 Buying Guide

A Peugeot 403 came as a saloon, estate and cabriolet, and CAR Magazine notes that cabriolets and estates are much harder to find than saloons. Confirm the offered Peugeot 403 matches its paperwork, then book an inspection that covers its construction and fitted equipment.

I used Peter Palm at CAR Magazine on buying a Peugeot 403 when preparing this November 7, 2026 guide. Those sources describe the model engineering and historical context, not every surviving chassis. So, the checks below turn that background into questions for a seller and a workshop; they do not assign a failure rate or current market value.

Choose the body style and check the papers

A Peugeot 403 came as a saloon, estate and cabriolet, and CAR Magazine notes that cabriolets and estates are much harder to find than saloons. Its Pininfarina-styled body was Peugeot’s second monocoque design after the 203. Ask for the chassis number, engine number and registration papers before you compare prices. A cabriolet or estate should come with documents that prove the body is original to the car. Have a Peugeot specialist confirm what belongs together before rarity becomes part of the price.

Inspect the monocoque on a lift

The monocoque body carries the load, so the sills, floors and suspension mounts matter more than the paint. Put the car on a lift and ask the inspector to check those areas along with the wheel arches and boot floor. Look for filler, fresh underseal or uneven panel gaps. CAR Magazine notes a transverse leaf spring at the front and coil springs at the rear, so check the mounting points for both. Ask for restoration photographs and write down areas the inspector could not reach.

Learn the column shift before judging the gearbox

The 403 has a column gear change with an unusual pattern, according to CAR Magazine, with first away and down and top gear towards you and up. Ask the owner to show you the pattern while parked before you drive. Gears should select cleanly once you know the pattern. Earlier cars had an overdrive fourth gear, later changed to a direct ratio, so ask which gearbox is fitted. Drive goes to the rear wheels through a torque tube, so ask the shop to check for noise and leaks there.

Look after the engine and original carburettor

CAR Magazine describes a 1468cc four-cylinder with an aluminium cross-flow head and a Solex carburettor, and it says aftermarket copies have not been well reviewed, so rebuilding the original is preferable. Ask what has been done to the carburettor and whether it is the original type. Arrange a cold start and a warm road test, then check for leaks and overheating. Ask for invoices for head and cooling work. Get supplier answers for missing trim and glass before you agree a price, since a cheap car can cost more if parts are scarce.

Put the identity and import file beside the inspection

The physical chassis identifier must agree with the sale documents before a report is ordered. Use our VIN identity checks to organise that comparison and our imported-car report guide to understand why foreign history may be thin. Ask for original registration, import and ownership papers as applicable. NMVTIS offers a U.S. title-history route with defined coverage; it does not certify a bespoke build or replace foreign records. A fake PDF can disguise an ownership gap, so verify evidence through the issuing source rather than accepting a seller screenshot.

Agree the specialist work before leaving a deposit

Tell the shop which version and components it will see, then agree lift access, a controlled road test and a written description of limitations. Our pre-purchase inspection checklist helps frame the appointment, while NYC used-car guidance recommends an independent mechanic. Ask the specialist to separate immediate safety work from cosmetic preferences and optional upgrades. Look, a repair estimate is useful only if a supplier will actually provide the required part. Have the shop obtain a response for any known missing item.

Keep the offer conditional on the findings you care about. Put any seller repair promise in the purchase agreement. If the workshop cannot establish structural condition or a route to a needed safety part, defer the deal rather than inventing a discount. The final decision should reflect the documented car and your intended use, not a figure copied from a launch story.

We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Wholesale reports cost a few dollars; confirm current coverage and the total at checkout. A quiet report can miss unreported repairs. Keep the independent inspection even if the seller sends an impressive PDF.
