Have put 40000 miles on my LS in 2 years. It is great. Have only had to take it in to have the AC head unit replaced, and then just GTO (gas, tires and oil) for the rest. It still handles great, and i get about 20 MPG driving a mix of city and highway every day. Just a great car.
The V8, gives it great get up and go. 6 CD in dash player.
Little better material inside. Larger rear brake pads they wore out at about 35000 and the fronts don't look like I have touched them.
