I have a 96 LS 400 also. Bought it 3 years ago with 136K on it and have run it up to 270 clicks. Motor and transmission are tight as ever but I did just drop $1700 into the front end.....upper control arms, ball joints, etc. Now I am at the crossroads of letting this thing go or keeping it as a back up. Best car I have ever owned. Joy to drive, handles snow well (with aid of Blizzaks), and dangerously fast.....capable of 150. Have pondered letting my 24 year old drive it until she figures out her car situation......could sell it to her (meaning GIVE) or use it to keep some of the miles OFF of the Cadillac I am picking up next week. I am not surprised to hear about one turning 500 spins. Very impressive car.
