I am 17 and right now I share a 2003 Cavalier with my sister. She is going to college soon so I will be purchasing my own vehicle. I have been looking around on Craigslist and I really like the Cadillac CTS. I dont really want to spend more than $10k so that leaves me with either the 2003 or 2004. Is this a good car to consider or should I go with something else? I have considered a truck or a mustang but trucks gas is not too great and the insurance on a mustang will be really high. Will the insurance on a CTS be really high? Also, do these years of CTS's have a lot of problems? Any advice is greatly appreciated.
