Im currently thinking about buying an M6 either on a 06 or 07 plate as ive just sold my mkv R32 .. im looking at one M6 which is completly stock and has ac schnizter kit on it and the question is this .. I like the look of the Eisenmann exhaust upgrage etc and map .. stage 2 i believe? Im wondering about perfomance gain .. costs and how it effects fuel consumption too and also would it then ivalidate the bmw extended warranty .. and if so could i have go too outside dealer for different warranty etc.. I would be grateful for any replies as this is easier than ringing around places to speak to different people etc .. could get a head start here lol! The other car im looking into is already hamann converted, so probably wouldnt do much with it, but the stock car is in white and i love the color.
Thanks in advance
