I'd take touch screen Nav, Blue-tooth and remote start from the STS-V and put it in the CTS-V. For the price of an STS-V you can take the savings and mod the hell out of CTS-V and stomp on the STS-V. I think the STS-V is going to be nice but I hope like hell it can hold up the V name when it goes up against its competitors. The CTS-V holds its own, still. Again, I think the STS-V is nice but not for that price but if you can afford, why not?
