Were any of the problems there when the unit was picked up/during PDI? I for one won't hand over final payment until I go thru the unit/PDI and THAT'S after I already stopped by to look it over really well after it arrived at dealer so they can fix it before I actually pick it up. Yes, I'm only a couple miles from my dealer, but shouldn't make any difference cuz your plunking down a good size chunk of change regardless. So if it takes a couple trips, it takes a couple of trips.
However, if you're buying at a location that's 10+ hrs one way, it should be noted/documented that upon PDI, any discrepancies will be fixed while you are there and if it requires you to stay overnight or 2, dealer picks up the tab while you wait.
Like others, these problems posted by OP sounds a bit fishy.
