Audi TT RS MTM vs. BMW M3 E92

Hi guys, I’m still looking for a replacement for my M3 E92 and I’m currently swinging between me to get another M3 E92 or a TT RS from MTM “refreshed”. The TT would have 400 hp, already a Bilstein chassis, Eisenmann AGA etc. and also only 18 thousand KM run… For the TT speak all-wheel and above all torque. It has about 550 NM and the M3 “only” 400. That comes from the turbo … still the TT is a little lighter about 150 to 200 kg… pure from the acceleration g the TT should go forward slightly more tactile, I think half a second to 100 and about 2 to 200 … VMAX, on the other hand, is higher with the M3 (removement of course provided). I find the topic really very difficult, all-wheel against rear drive, vacuum cleaner against turbo, V8 against row five cylinders etc. … price-wise both do not do much about the 40 bills in the purchase and in the maintenance should also be similar… So then I’m curious how you see the comparison like this!
