I just brought my 99 gsx home today and I think the motor needs rebuilt. Whats the average price a shop would charge me to get it rebuilt? And are there any common problems the 4g63 has to be aware of? Thanks guys! I just bought this for my wife as an anniversary present to replace the one she had that I rolled when we first got married. LOL! I rolled it 3 1/2 times. I am really wanting to upgrade stuff on it and make it a really nice car for her/us!
