American source, American winner! (n)
Cts-V:
One fast car & probably the best sedan ever from Gm! Looks & performs great! However, it's price-tag is very high for a car that won't keep her value in next couple of years... American! She does competes with C-63 but does not belongs to the segment of M5! Nothing unique under the hood, the Ls is Gm's best, making their cars better!
M5:
The pioneer of sports-sedan since day one! The phenomenal V10 is out there for years now & the new motor is due with the next generation! M5 is not rival of compact performers like Cts-V & C-63, she competes with Sts-V, E-63 & S/Rs-6! M5 is not the just fun to drive & about driving fast, it's a unique feeling of motoring! (y)
C-63:
She is a great performer, a real rival of Cts-V here. I admit, Cts-V is faster then C-63 but we must believe, Merc is better educated car & is among the best engineered cars on this planet. C-63 is a car to live with & Cts-V is a car to live around! In real world, no wise man would take a Cts-V over Merc, unless he is a pure red-neck! (H)
