Mileage of your current car will help..
I had 3 standard exhausts replaced under warranty on my 182 in less than 12k..i then gave in and bought a yozzasport system, tho that was the only problem i had with it in the two 20 months i had it before i traded it..
I guess mine was a 'good one' tho..
My mate bought an identical car from the same dealer, his exhaust was fine but his climate control/air con packed up after a year tho again it was replaced under warranty...both cars were December 05 55 plates i.e the last of the 182's so most of the problems had been sorted by then.
