I am looking at a 92 SC300 with 160,000 miles on it. The timing belt was changed a 125,000 and it seems to be in pretty good shape, but it's also been detailed to the max. So my long winded question is , how many miles is too many on this vehicle...do these things go 200 + regularly, or should I be looking for a new motor soon? Oh yeah...the guy wants 6 grand...seems fair..
