‘99 tahoe - 150k runs like a watch - of course most of the parts are new now.
I have 2001 Excursion with 165,000 miles. Besides the fuel pump (which is caused by my wife driving on empty) and the issue with the two spark plugs, no issues. My son found a you tube video on how to reinforce all the doors seal with surgical tubing. So for $75, all the doors seals are better than new, all the rattles are gone and wind noise was reduced. We were thinking of selling it because the kids are grown, but why?
