We have about 67k on the van and will likely keep it to near 100k or so. Wife doesn't work any longer so that could be several more years. I'd buy another Hyundai without question.
Sync wise, I love it. MS thing doesn't bother me. I think the Honda/IBM version in my previous Honda and Acura products was better and more refined, especially given that was nearly 8-10 years ago, but this will do.
Good luck.
