But, the saying is true - the purchase price of an old MB is just thefirst repair bill. Because they have such great body integrity (even a 20 yo Benz can feel like a new car) it sieasy to be lulled into thefeeling that it will last forever. well, any car will last forever, depending how how much you want to replace. Unfortunately, the 500E had some design flaws - there was not enough room in the engine compartment of all that engine, and electronic parts tended to cook. I replaced a throttle body, a $1200 part, three times, and it had been replaced onece before I bought it.
I know the early GS 300s were marketed in Japan as a Toyota - are parts available from Toyota, and if not, does Lexus charge a premium for comparable parts?
