Despite its relative youth, corrosion can be savage; and it’s this that’s most likely to turn a 5 into a parts car. Don’t ever buy one without first inspecting it from underneath, as the floorpans, front subframe and chassis rails all rot badly. Expect corrosion behind the headlights (inside the front wings), in the sills, and behind the front and back bumpers. The latter is hard to see but if things are really bad, you’ll see see daylight if you look inside the boot. If you’re looking at a GT Turbo there’s also the spectre of poorly repaired crash damage; a lot of these hot hatches have been crashed or just badly modified. Panel availability is good; decent used doors, tailgates and bonnets are plentiful. Renault can supply more bits than you may think but with so many cheap used parts, very few owners buy new components for their 5s.
