here's my thoughts
first off why people compare a cts and a 5 series is beyond me... IMHO the cts is a 3 series fighter.. not 5 series
if thats the case a new CTS-V destroys a new m3 sedan
for the m5 comparison... when cadillac first came out with the original cts-v, i think they just wanted a little market share, then on the re-design, they took aim to take down the M series cars.
BMW wont be loosing any m5 sales and probably doesnt give 2 shits about a cts-v for that, and they will just look to top Audi and MB top line models.
What they should be worried about is the CTS and CTS-V taking sales away from 3 series cars, and I know they are.
What I think sucks is one of the mags did a compro between the c63, IS-F, and m3 sedan, they should have added the CTS-V in there because i think thats the correct market spot for it
