That's a lot of kms. My 2002 GC 3.3L Sport had 370,000 km on it when sold to a neighbour. He drove it for a year or so and sold it to a friend in Cape Breton who was in need of a vehicle. It was still working good, so he said. Likely approaching 400,000 by now.
My 05 limited has 218,000 miles. Just used it on a 2,100 mile trip to DC and back from Naples, FL. Just sanded off all the clear coat that was peeling on the roof and mostly one side. Spray painted it with cans from the internet and it looks almost new. Got a new transmission about 3k miles ago but not sure that that was the problem as new front discs stopped the shaking. Been thinking about upgrading to a newer year but the only thing I'd be gaining is phone bluetooth. It's my 3rd vehicle besides an 05 Mini S convertible with 118k and a 95 XJS convertible with 200,500k, that's not counting my Honda Silverwing 600cc scooter with 25k. I didn't put most of the miles on the Jag or the scooter. The van and the Mini I did. I'm single.
