2008-2013 Cadillac CTS General Discussion Discussion, 08' Cts Prices in Cadillac CTS Second Generation Forum - 2008-2013; Saw over at the CTS forum this sticker price:
Vehicle: 2008 CTS
Selected Style: CTS V6 DI PERFORMANCE SEDAN
If I go to the Cadillac web site and look at STSs, the cheapest base price for a V8 is $52,555 before adding any options. After adding Nav, Sunroof and Premium paint (all on the CTS you quote) the STS comes in at $57K MSRP. The STS V8 is rated at 320 HP. The CTS you list is a V6 rated at 304 HP. Not much difference. Furthermore, the CTS you quote has the optional All Wheel Drive.
So, $48K for the CTS vs $57K for the STS. STS has only 16 more HP. CTS has AWD. So, the butter question would be "Why would anybody buy the STS?"
You can buy a V-8 STS for that same sticker. Why would anyone buy a CTS (6-banger) at that price?
Just off the top of my head, the 2008 CTS V6DI gets better gas mileage, has a larger fuel tank (18 vs. 17), greater fuel range, newer and better interior design and assembly, music hard drive, retractable nav screen, larger sunroof, fold-down rear seat, lighter vehicle, new exterior design, probably holds it value better,... For it's cost, the STS needs the new interior, a larger fuel tank, and more rear leg room.
