I'm looking for a nice 80 for around $16K. I visited a used car lot in Los Angeles that had 2 LX450s, both with about 100K miles. I drove both and they seemed excellent. But I watched the sales guy start each one up to back it out so I could drive and noticed smoke in the exhaust right after the engine turned over. They did not continue to smoke, but this really makes me nervous. It was not cold in southern CA on Saturday, so I dont think that was it. Anyone notice this on your 80's?
