I'm looking at a 2008 CTS with the 3.6DI engine, performance package and six speed manual. Car has about 22k miles and is Black Cherry. It is being sold by a local Cadillac dealer. Car is very clean overall, 1 owner and according to the CarFax got pretty consistent mileage so it seems it was more of a weekend/leisure car.
I went to look at it, went for a test drive and all. No odd noises, started right up, idled nicely etc. No obvious leaks under the hood, actually looked surprisingly clean for a 6 year old car. Clutch and transmission both felt very smooth. Dealer was more than happy to fire it up and go for a test drive. Engine was more than ready to climb through the revs and felt more than capable pushing the 4500 lbs of Cadillac around. Under 2,500 RPM (which, with the 6 speed, was pretty much always), it was very quiet and composed but with just a little more of a push on the pedal, it certainly didn't hesitate and the power was accompanied by a very satisfying growl from the engine.
I've read quite a bit, mostly about the timing chain problems and oil consumption with the V6/DI engines. I checked on GM's recall site and the only open recall listed is for the ignition (it is a standard turn key) so it seems that the car has at least had the re-tune in effect for the timing chains. Is there any way to tell about whether any timing chain service has been performed? Is there any way to know about the oil consumption (as in, is it outside acceptable range) without simply purchasing the car, driving it and keeping an eye on the oil level?
The car wouldn't be my main form of transportation. I would imagine it would probably see 6-7k miles a year, most of which would be short (15-20 minute) highway trips and the rest being either short, easy trips to the store, etc or otherwise more "spirited" driving when the occasion arises ("spirited" not meaning redline runs but just rides on nice, curvy back roads).
I really like the car. It was a very pleasant ride, the seats were comfortable and it just felt nice to sit in, very quiet and composed. Everything seemed to work and like I said, there were no obvious problems/odd noises or anything of that sort. The car sat very flat through corners and seemed very ready to just keep going. The color is nice and I've never seen another CTS around here in seemingly any color but black or white. This is one of about 6 or 7 manual CTS in the area (within 50mi of me), at least 2 of which are CTS-V models, 3-4 years older with at least double the mileage. This is the only manual, 3.6DI CTS within 50 miles that I can find, I just don't want to "settle" on the first car I've really looked at and end up regretting it because I have (seemingly) such specific requirements (manual being the biggest one and minimum of the 3.6 V6 being the next biggest).
I guess what I'm really asking is, is there any reason I SHOULDN'T buy the car? I already know about the timing chains and oil consumption and the other miscellaneous little interior quality issues.. GM has issued an "extended" 10year/120k mile warranty for "premature timing chain and with a mere 22k miles, I don't think I can go wrong.
