I don't think I will have mine to 300K.No where a mega miler 'yet', but I bought mine with a salvage title with 80K, and it now has 250K roughly.
I was bragging to someone about this when he said he had just traded in his 05 Chevy PickUp with 315K on it. It was still running perfect, just wanted a change.
I have to admit that though I love the fuel economy, after ten years I sometimes find myself looking at replacing it with something a bit bigger and quieter. It'll be time for a suspension refresh again soon, that could change my outlook on it.
