Purchased in Jan. 2001 as a certified pre-owned with 20,000 miles. It was in pristine condition. And it still looks like a new car at 112,000 miles. Try to find a cert. pre-owned GS V-8 today. The big point of this is what my Lexus mechanic thinks of the GS400. He is an older guy with lots of knowledge and experience. He said, "don't get rid of this car". No more need be said.
Keep front and rear wheel toe-in near middle of allowable range. Put front camber around -.3 to -.4 degrees; and, rear camber around -.6 to -.7 degrees. On my car, it improves tire life & lowers tire noise.
