I just said i'd prefer an MG ZT 260. its a british car with awful build quality that gets 10mpg and slides around corners like a mad thing. that hasnt got a german badge neither, and the engine is ford...
however, despite being sport tuned, you know that it will take you to and from work, and whilst being compromised in comfort from the exec saloon, it will still be pretty nice to drive.
The caddy, will not be. they went full out on the sports end, and none of the luxury, and being american, they need to work on that alot!
Notice that, with the exception of the lotus carlton, all the big sports saloons have been luxury brands that have added a little spice to their models.
Look at the best sports saloons we have now:
Maybach 62
Bentley Arnage
Audi RS6
BMW M5
Mercedes CLK
Jaguar XFR
Maserati GranTurismo
Notice these cars are daily drivers, and you can actually live with them. Caddilac has never been teh pinnacle of interior flare, and i doubt that putting all the power in and making it go around the 'ring sub 8 minuites is going to help.
the words 'suspension like concrete' come to mind
