I bought a used Lexus LS 400 with 94000 miles from an auction 3 years ago thru a dealer friend for 11K. The car is now at 152000 miles and only work I have done on it is routine... brakes, timing belt/water pump, spark plugs, wires. This is the best ride you can ask for the money as it still rides and feels as if it is a brand new car. Every person who has driven my car has accepted the fact that this is a very smooth ride.
Extremely quiet cabin. No road/engine/ tire noise. This is no joke but it is so quiet, I have hard time staying awake on highways. Very strong engine. Very powerful at 260HP. Nakamichi audio, looks, climate control system.
Relatively expensive to repair unless you can find cheaper parts and a local mechanic to do the work. But the ride is worth the extra money you may spend on expensive parts/labor.
