I went to look at a 1996 Tahoe LS 4dr. tonight. It appears to be in beautiful shape with no rust. The engine is clean enough to eat off of and doesn't appear to have been cleaned up for sale, other than some Armor All on the plastic parts. It has 124,000 miles on it. How long would the motor and tranny be expected to last in a well maintained truck like this? Are there any known problems that I should be looking for at that mileage? I don't want to get into a money pit if I can help it. The truck really does appear to have been very well maintained and he assured me that it was mostly highway miles. Also, what do you think a fair price might be for this truck? I live in NY. Thanks in advance.
