Hey guys/gals. I am the proud owner of a Cadillac CTS4 (its the AWD version with the DI V6 engine)

The car gets 304 HP but just always seemed sluggish. I LOVE the interior and the features, such as being able to pause and rewind live radio, the adaptive headlights, heated washer fluid, keyless access and so on...

I was looking into trading my 08 in for a 10/11 Audi S5. I LOVE the exterior of this car. More than the Caddy. The interior is OK. But mostly I am interested in performance / acceleration. I need to get back into a V8!

Anyone have experience with both?

Also when shopping for an S5 what should I look out for? Any known problems? Any advice? Thanks!

 

First post, but this is the perfect one for me since I also own a CTS coupe. I have the RWD 3.6 318 hp so just slightly different than sandcracker but I'm sure we're looking for similar advice. Also, figured I'd bump this thread in the hope that others may have advice on a S5 to be aware of. I test drove an S5 back to back with the CTS-V, and while I much prefer the looks of my CTS coupe, I was surprisingly VERY impressed with the S5. Not looking to make a move quite yet, but probably in the next few months so I was doing some early research with some test drives.

Also, cross shopping the MB E550, so if anyone has input on that for comparison it would be helpful too, although I definitely lean more towards the Audi.
