What year? I got a 93 Toyota - one of the most fucking reliable critters around, but the age is making parts wear out with only 149K on the clock.It’s only 60k on it. Got it from my granddad who’s a mechanic
And low mileage on a Jag of that era is NORMAL. Back then, the joke when you told someone you had a Jaguar was for them to ask what your OTHER car was...
They needed to have tuneups every oil change, and the tuneup required manual resetting of the valves. So if your grandfather wasn’t a mechanic when he bought it, he probably became one in order to keep it without going broke.
