My dad just picked up his saphire black 525i w/ premium and cold weather packages. I think it has a couple of other things but I don't remember right now. I'm pretty sure it has 17" rims. I thought those only came with the sports package though.

How many RPM's should he keep it under and for how many miles. (It's a 3-year lease, is this even worth it?). Any other new-car things he should do/worry about? It looks/feels great and we want to keep it that way
