Between the Audi A4, BMW 3 Series, Cadillac CTS and Mercedes C350, which one do you guys like better? (recent models) Personally, I like the A4 even though it's got the least horsepower.
Mercedes would rate the lowest on my scale, never really been impressed with any Mercedes offereings other than the AMG line. Of the remaining 3 I would go with the BMW. However if you change the CTS to a CTS-V, the 3 series to an M3 and the A4 to an S4, I would take the CTS-V without no questions asked. It is an amazingly well put together vehicle that can take on either of the other 3 without any difficulty. It surprises me to say this since I have been a fan of the Bimmer for years now.
BMW! Mercedes have always felt cheap to me. Like comparing a Nissan to a Toyota... Toyota being better quality. So go for the BMW and high quality. BMW handles very well and feels solid, well-put together.
