a Vauxhall Cavalier 1.8GLi, detuned SRi engine so went ok however the rest of the car was not up to it, brakes, tyres and suspension were awful, as a consequence it understeered and locked the front wheels at every opportunity meaning I left the road on more than a few occasions - traded it in for a VW Scirroco after a few months and then successfully managed to go around corners :P
