As I wrote in an earlier message, I'm about to lease a 540i 6 spd. The dealer has given me my choice of silver or black, both over black, and both completely loaded apart from navigation. On a 36 month lease, 12 k miles and w/ $7,500.00 down, $559/month including taxes. I'm not too sure I can get by w/ 12 k miles, and whereas I know an M5 would lease for more, I'm not sure I wouldnt rather pay more and get the M5. Any advice?
