Does that really matter too much in a Race Car, that'll look like a serial killer's death-machine anyway with all the added Fins and Blades.....?
Calibra is for sure, my favourite, I've loved it since GT2, it's always been better than the Alfa from the similar era. Also, '94 is my Birth Year, so we have a connection there too!
My favourite is the Alfa followed by the Astra. I bought a Calibra super touring car based on what people have said on here but i found it to be very slow compared to other DTM cars. Maybe it needs an engine rebuild, but in a 3lap race on Tokyo i ended up 30secs behind. The Mercedes CLK seems the fastest DTM.
Might have to revise my opinion -- just picked up the CLK from the UCD, took it out on the Nordschleife and immediately took 4 secs off my best time with the TT, even with a bit of ham-fistedness along the way. This is one quick car.
