When I was shopping for an LJ in 2007, I drove an '06 LJ with 13K miles, all stock. It shook like a belly dancer! I told them I'd buy it if they had it fixed within a week.
They also had an '05 LJ on the lot with 10K miles. Saturday morning came, time for pick up. I called, they said the 06 was still in the shop.
I told them to prep the '05, I'd be there to pick it up in 2 hours
