For a daliy running 406 coupe is far way behind , good for a spin though , i have the 407 coupe, since i bought the car i had to repalce couple of things such as starter motor,AC compressor and of course the parts are cost hell of a lot , C** ***T people are suck at this thing and the parts are not availbale in SL for both 406 and 407 coupes, but its a good ride and something rare that u dont see everyday
