when my 15 y/o and her friends get in my E39 (and it ain't nothing special compared to a lot of peoples' cars on this board) I'd say they love riding in it. For some strange reason they love how the interior lights go dim like in a movie theatre vs just going out like in most cars.
As for the ignition key situation...had I known better I would have negotiated for an additional key to be made by the dealer. My car came with only one key as well. It's one thing for your IROC-Z to come with only one key since it costs only six bucks for a new one....a hundred dollar key is a totally different situation. It all depends on your negotiating skills and research. Also, if I had researched more I would have bought my E39 with sport and cold weather pkgs too.
