Is he crazy? 120,000 miles is nothing for a toy, 150,000 is nothing for a toy. Hell, my 91 has over 200,000 on the stock engine and still has high 190 psi compression with all cylinders within 3 lbs of each other. Getting that specific with that low of mileage for a toyota is going to be pigeon holing him and really limiting his search!
One kid I know bought his 92 with over 300,000 miles on the original 22re, and although it was a little slow, it still ran fine. I bet all it needs is a re-ring and timing chain and its good to go for another 100,000 miles at least.
