my STS is a nice looking car but I have problems after problems one of the air suspension went out cost me 1000 dollar to replace it right now it's making noise. i beleive it's a electrical problems now. I will never buy another cadillac. it doesn't hold its value, The back bumper coming apart. and it hard to find someone to work on them beside the dealers.
Nice car. I have the V8, LOTS of power and pretty good mpg. Handles great, looks great. Had some issues with windows, misc noises.
