what i dont understand is how can you say an m3 uses a lot fuel?

i drove it for about a month and yes it was thirsty,but not any more than any other m3 ive had,so i know it was ok.it was a lovely 90k fsh car which drove really well.like i say when it developed a silght missfire on no4,rather than just change the offending coil pack i bought all 6 and did them all- not cheap!

you can picture it.......geeky guy walks into garage"ive just bought this m3 and it doesnt seem quite right,a bit thirsty and i think it may have a slight misfire-can you have a look for me please,whatever it needs just do it"garage owner rubs hands and thinks of where in the world he is going on holiday thanks to this muppet or how much white stuff he can throw up his nose this weekend,paid for by said muppet!
