The only problem we had is a bad cable in the sun roof - replaced for almost nothing after the warranty period was up. Bought this vehicle new and now has 125,000 miles. Serviced the vehicle at required intervals at Newport Lexus which has excellent service. No repairs made to this vehicle other than brakes. We also own a 2001 GS 430 which now has 220,000 miles - has never leaked oil and the only repairs have been a radiator replacement and engine mounts - both replaced at 200k miles. I drive the GS and push it real hard, but it does not care.
Excellent power, great fit and finish, reliability, stereo is amazing, general looks, safety, OEM tires lasted 68k miles, bought the same kind and have over 57K miles - still going strong. Michelin Cross Terrains.
