On my Pug 306 1.6 XS.
In 3 years, including purchase, repairs (Head Gasket, Valve Guide Oil Seals), Crash repairs (Rear Beam, Bumpers) and modifications (Christ, rear beam disc conversion, cams, exhaust, lower than your nan's tits, bodywork mods, spoiler, side skirts, etc etc it just goes on!) it cost me £9,000. It was written off by a moped when parked and I ended up with £2,500 pay out. TBH though it failed MOT the day before so I was happy to see the back of it as it was about to cost me another £500 or so to get it through. Then I was going to whack a 2.0T 405/6 Engine in it.
Said i'd never modify again, that lasted 2 cars, then the 182 came along.
