Saw this ad on Craigslist where someone is selling a 94 J30T with 299,000 miles on it for $1400, and claims it is still running strong. I have 199,523 miles on my own 94 J30T, and was thinking of selling it when it hit 210,00 miles and needed its next timing belt change, but after reading about one going 299,000 miles maybe I should keep it a while longer. I read of a J30 with over 500,000 miles on it and it supposedly still had its original engine and transmission.
