Question for the OP. How many miles on the car and how old? It sounds like you said 6-7 years old and you expect to get another 6-7 after a rebuild. Won't the other componants start to fail over the next 6-7 years, such as transmission, shocks, struts, ball joints, bearings and all of that other stuff on the car? As a matter of fact my most recent failure on my Aveo was my brake light switch. so although you are saving the price of a new car, you are not really getting a new car. This one might nickle and dime you after you invest all of this money, but as you have ordered the parts, it might be too late.
