What is the best Cadillac now in the V series?

Depends what you're looking for.Cadillac would like you to believe that the XLR is the best, and if you're looking for a convertible they'd be right. If you want a 4 seater and can afford the STS then its the best.If money is an issue, the CTS is a very fine car, just not quite as fast or refined as the STS.

The XLR. I like the looks of the CTS and I've never seen a STS.

That really all depends on what type of vehicle you are looking for. V series is just the engine. Are you looking for a sedan, coupe, convertible or something else? I just leased someone an STS last week...it's their second and they love it!

I say the CTS-V is the best. I love the look of the sharp styling and of course it is the cheapest V-series. Did I mention the Corvette engine!
