When I bought my E92 in March of 09, they offered me a brand new 2008 E93 for $60k. They had 3 on the lot. All with stickers of $75k+.
$51k for a used '08 E93 doesn't seem completely unreasonable taking this offer into consideration. Still almost too good to be true, but certainly more possible than an '09.
