I had a Saturn ION for 2 1/2 years. The first year-and-a-half it was great. After that, it was hell every day.
It got to the point where every other day or so it just wouldn't start. Not the battery, not a fuel pump, not the transmission, the starter, sparkplugs, anything. It just wouldn't start. I would have to get pissed, go sit in the house for about 10-15 minutes, come back out and it would start fine.
I took it to everyone I could think of, and the Saturn dealership I bought it from had a combined IQ of 12. They were pains to deal with, and one day when I went up there to look into trading mine in, I was treated like crap and the salesman pretended like I hadn't bought this car from the same dealership two years earlier. He checked my credit without asking me and asked me if I was going to waste his time. I guess he thought that since I was young, I must not know what I'm doing.
So I left, waited a few months and got rid of it. I prayed to God it would start the day I traded it in. It did, and no one said a thing about any problems. I got my Ford Escape and it's been a trooper. About 26,000 miles later in 10 months, it still seems like it's brand new.
So needless to say, I'll always think Saturn sucks balls and will never buy one again.
