LOL........My '92 with the Iron Duke 2.5l has about 92,000 on the odometer.
It was owned by a little old lady up in the north woods, and it sat for years in a moist driveway.
I got it at auction with about 64,000 miles on it, and the rust will kill it long before the motor dies.
Replaced a few brake lines and the whole gas tank assembly so far............
One of these days, the unibody will go scrunch........and break right in two.
And the 2.5 will still be good to go....where, I don't know....LOL.
