me and wife just bought one today and i was very impressed...electronic power steering is real nice and the door shuts solid...GM has some good cars coming down the pipe, i think the domestics are very underrated...car was assembled in Ohio, engine and trans in USA which is important to me cuz i work at a supplier and want to see more jobs and mfg here...and as a btgoer, i was excited to own my first OLM...i will go with SOPUS and M1 like i did on 05 sunfire...what do you guys like for oil in the ecotec?
