This is a great car and don't take my opinion wrong it will get you around even if you bit sh!t out of it, but its a first year for that car and it tells it all, basically you will constantly run into electrical problems with check light of all kinds, i and my roommate owned all bimmers from 90s era then we were in uni, and the best things trips we had was in those cars but even proven models were not easy to maintain basically because we abused them to the limit. I dont know anybody personally who owns 2002 7er but i base my on opinion of friends who had first year production cars of audi's, vw's (mainly Toureg), and benzes (w220) in beginning of 2001-2002 and you should have seen their frustration with little things even though then cars worked they rolled like pimps)
I really don't know what to recommend as i was looking for one also but bought A8 couse had to move up north where 4wd is a must and the price was better since it was older body with super low km's plus i didn't want to have all the trouble with a car with no trusted mechanic, but to be honest i still question myself if i could have gone with a 7
But since the car is getting even older, i wouldn't recommend it (((
On the good note buy yourself a 2001 740 and a summer pimpmobil like i did check it out green/orange hand made engine 230E a real classic with orange fogs and I only got it because the guy took a trade for my old blown engine 7er ))) but its the one of the best deals i ever got)
