Car fiasco

About 2 weeks ago, Richard let me take him to work so I could have some freedom and do some shopping. (Let me tell you, having no car all day and it being freezing outside really gets a person stir crazy, at least some good projects have come out it). Anyways, I took Richard to work and got some things at Joanns and Target and then went home. On my way to pick Richard up from work (about 35 min drive) the check engine light went on. This used to happen all the time in my old car, so I didn't worry much. Then I happened to notice the temperature gauge was pretty close to H, I was about 1/2 way there so I thought, "i'll be fine till I get to Richard". 5 minutes later it was past H, so I decided, I better get to a gas station. Then the car started slowing down as I approached the exit....to the point I was going 45 instead of 65 when I got there. Then the car died as I stopped at the end of the exit. The teenage boys behind me pulled over and told me they could see it smoking. (oh, Libby started crying about the time the car started slowing down...so that really helped me stay calm....).  The boys looked under the hood and using their vast amount of knowledge told me they didn't know what was wrong, but that my oil was really black and I should let the car cool down and put more oil in. They also kindly pushed my car to the side of the road, while I held the screaming baby.  It was very cold and very windy. Luckily, earlier that day I had dropped off a bunch of baby food to my friends Jamie  who happened to live 5 minutes off the exit I died at. So I called her for help and her husband Bryce came and took me to the gas station for oil, put the oil in my car and let me stay in his warm car while we waited for Richard and his boss to come. Bryce also got me a number for a towing company. We had the car towed back to a Rexburg auto shop. The auto shop gave us a quote/diagnosis. I think we blew a few head gaskets and something was wrong with the coolant system. They estimated at least $2500, but they said it could easily be A LOT more. So after much deliberation and opinions from many people, we decided instead of spending that money to fix the car we would put money down to get a new(er) one. We got a 2005 Chevy Impala with only 66,000 miles on it (which is WAY less than any car I've driven).  It's pretty gangster looking, which is funny. Gold, with black stripe and tinted windows. It has a screen for a DVD player in it, but we have yet to figure out how to play a DVD. There aren't instructions and we can't figure it out. (the cd player did not work as a DVD player). They took off $1000 for giving them our broken car. Anyways, it was quite the fiasco and Libby was up more than an hour after her normal bed time by the time we got home and was quite the grump.
