So I'm finally an owner of my very own saturn sky. I've been an admirer from a far for years but never bought one... This week the perfect one showed up at a local auto auction and I took it as a sign that it's time to get a sky. Paid the reserve price of 5k, had a clean car fax, info from when it was traded in, dealer inspection from 3 months ago etc. Thought I got a great deal. As I drove the car today it began learching and coming to a very tough stop, then the check engine light came on... Any ideas what's going on? Did I make a $5000 mistake?
