I recently purchased a 2001 740i with the Sport Package and only 55,000 miles on it. I have had it thoroughly checked over and all maintenance brought up to date. It runs great but I really don't know the details about what I have. Although I am a retired Mechanical Engineer the complexity of this machine has me overwhelmed. Just for beginners, what does the Sport Package include? While I have put new tires on the wider, stock rims and new snows on the extra set of rims that were included, I'm still being warned to not even consider driving in the snow. Is this extreme concern justified? I will appreciate any replies and I'm sure to be back with more questions about "Grandpa's new toy".
