1994 Volkswagen Golf 1.8L Petrol · M345 BLB

Wikipedia's Golf Mk3 article attributes the model's rarity today partly to quality issues with the steel Volkswagen used, which it reports led to significant corrosion in the floor pan, door sills and rear hatch, with independent mechanics and MOT testers advising buyers to inspect for rust, holes and patches in the floor pan. The UK Golf GTIforum buying guide reaches the same conclusion from the workshop end: sill rot where the rubber door seal meets the panel and at the front jacking points, floors rotting from the inside because the drain bungs let moisture in, and a driver's-side inner wing that looked clean under tidy underseal but had actually rotted through - a structural MOT failure.

RAC's Golf GTI Mk3 used guide warns that the manual gearbox is the one area needing careful checking on high-mileage cars, which can have worn bearings needing expensive repairs, and tells buyers to get any noisy box inspected. Its VR6 guide repeats the theme from a different angle: graunchy synchromesh in second gear, unevenly worn tyres and worn shock absorbers are all evidence of an over-enthusiastic previous driver, on a car RAC notes is more complicated than its smaller siblings. Wikipedia's specification table confirms these cars used four- and five-speed manual boxes and a four-speed automatic, so a replacement casing is a period-correct but scarce part.

RAC's GTI Mk3 guide says corrosion is uncommon on an honest Golf, which means a rusted one should scream badly repaired accident damage: a bent chassis will have caused misaligned panels and subsequent corrosion, and it advises steering clear. The GolfGTIforum buying guide makes the same point from the other direction, documenting cars whose sills had been bodged earlier in life, whose rot was hidden behind the plastic arch kit - described as a terrible design that holds moisture against the bodywork and as good at hiding rust when selling - and owners wondering how a heavily patched car had passed its past few MOTs. For a 30-year-old Mk3 this is the single most common trap.
