I am very sorry as i completely failed to understand that you were looking for a trade , unfortunately , i'm only selling this car to buy an Imola red e39 .Also i have had 2 M3's before and lastly convertible is not my cup of tea .But i appreciate it & Good luck in finding LMB E39. i have always liked LMB , estroil blue and laguna Seca blue ,but I think LMB is an Exotic color for M5 after Imola Red.
