Hi Jon welcome to the club. I would imagine the sat nav for your car would be quite outdated now. May be better looking at an aftermarket replacement? This could give you sat nav and bluetooth for the phone?
Difficult to say, I would say the decider would be whether or not there is any damage to rear suspension etc. Unfortunately, BMW parts are expensive so costs could add up :(
I agree with James. If you don't have a badge on there is leaves people guessing what it is which can be quite entertaining! :lol: All depends on how much you like traffic light grand prix's!!
