I am a former CTS-V owner (05, 09, 12) and a former '06 STS4 N* owner and am considering getting a high mileage STS-V as a third car and highway cruiser. I don't want to spend a pile of cash on a third car and am wondering how these cars are as the miles build up on them for reliability and cost of repair? I always really felt comfortable in our former STS but we did not put a ton of miles on that car so I really don't have a track record to go off of.

I have an 07 with ~117,000. Bought it at 93k with certified coverage. Of course that is expired now. When I purchased I went to the dealer (give them the VIN) for a list of repaired items looking specifically for "no problem found" complaints which would indicate a recurring issue they cannot resolve.
It is a third car for me as well. Used only around town on the weekends. I has been very reliable. All the minor issue that most people have like T-stat, rear bearings, ect had all been worked out by the previous owner. The story is not over yet, but I have been very happy with it. It does have a minor rear seal leak which I am ignoring due to the low use. I drip per month.

Diff seal is covered under recall, if that's what you mean. Just take it in.

Thanks guys. Keep the comments coming. Is the supercharged N* fairly bulletproof? How is it and the drivetrain at handling added power? A couple of the cars have revised programming and changed supercharger pullies. Do these mods take away from overall reliability?

I'm at 104,000 miles on my 07, it's been a pretty good car for the last 25K miles that I've owned it.

The only thing I'm having issues with now is one of the cats. I understand these cars are hard on them. Suspension and electronics seem to be pretty solid, everything works on my car.

I think the key is going to be overall condition when you are shopping. Mine was extremely clean when I bought it at 79K miles, it seemed the previous owner took good care of it.

160,000 miles and no major issues.. Only things I've had to do in the last 30k was replace a tail light that stopped working, a wheel hub, and still have to do the rear diff bushing. Oh and fill her with a lot of gas and a new set of tires and brakes.

Last comment, check the VIN with a dealer before you buy. It will tell you everything which was done at the dealer. They won't let you take the print out, but you can review it.

There is a harness under the pass seat that comes loose. If I remember right it's connected to the sensor that detects a butt in that seat. Comes loose easily if you're reaching down there looking for something. Look down there for a loose connection. I had the same problem once. No issues since making sure it was plugged in.
