It's tough to imagine being happier than I am in my 2013 750i x-drive. However, as I look to add another car to family fleet, I sure am "teased" by the value of 2013-16 Alpina B7's. Here's the big question where I need the Community's help -- What kind of additional maintenance expenses should I expect if I buy a B7 instead of a F01-F02? Thank you.
Maintenance is very similar to your 750i. Spark plugs are done more often. Brakes are bigger and will wear faster from the extra power and are pricy. Alpina does have a lot of parts that are specifically for them so getting parts is expensive and takes awhile.
