How bad is the 530i in the snow with a good pair of snow tires? It is comparable to driving a front wheel drive car with all season tires are much worst. Then by defualt, AWD would seem to be better, but is there a huge difference here. I am thinking of getting the 530i, but don't want to spring for the 530xi (lack of funds). Any input would be great. By the way, how reliable are the 06's to date? I would of course either purchase certified pre-owned or new.

Thanks
The difference between the two in the used market is more like 7-10,000
