Well my supra hasn't given me any trouble. 89 non turbo engine has never been opened it has 218k right now everything still functions. Things like valve seals causing me to burn oil is bad. But otherwise I'd sitll take it on a long trip, but I'd not because we have a camry now lol. But I swear it misfires or something once it gets going over 4000 rpm I hear loud snaps like guys who put cherry bombers on their trucks or whatever they're called. And honestly feel like it's faster in low RPM! But it still works.
Yeah working on a car as a hobby can be enjoyable. When you're rushed and need deadlines and it's 95 degrees and you're covered with oil and have aches all the time from bending around, that's suck I'd think.
Don't know if it's bad to keep responding as we've gone way off topic haha.
