This is my first post and I did skim just a bit through the questions before posting this, but here is my question. I have 5.5K to spend on a used car I need to last me about a year, maybe a 2. Through my search I've found two 02 Devilles, both have a clean carfax with 1 owner, one has 84k miles, the other 48k. The problem is I've had 3 mechanics tell me to avoid them at all cost because the North Star engines in those models are notorious for blowing head gaskets and it's not worth the risk. I REALLY love these two cars, they're immaculate and the test drive was great. I start a new job July 13th and I can't miss one day the first 12 weeks which is training. As Cadillac owners, what would you advise me?
