I don't care about the prestige factor, I just love the car, but I remember one time I had a car dealer looking at my car with another guy who had owned a CTS, the CTS guy said while looking at the exterior, oh that is just like the car you just sold for me, the dealer guy just kind of shrugged his shoulders, CTS guy walked away and dealer guy starts apologizing to me, like the guy had just insulted my kids knowing the pretty large difference between the MSRP's.
With the ATS and new CTS, you have distinct cars that can be recognized for their distinct qualities and that match up nicely with competitors offerings.
