Congrats! Can't help you on the key fob issue or electrical gremlins, but window regulator issues are common and a DIY fix. The skins needed a good leatherique job once you have some warm weather. Purely a matter of taste, and I know you are in deer hunter country, but, IMHO, the camo steering wheel and seat covers have got to go - just not a BMW fashion item, sorry!
. If the steering wheel is funky, a sew-on wheelskin leather is a good way to go. Glad to see you have three pedals and a real stick; make sure you join Ricky Bobby's MT registry and consider a CDV delete and UUC SSK to make that one fine-shifting SAV! Search the forum using those terms and you'll know what I mean ....
