From the original ED invoice pricelist:
335i coupe $34,360
Step 1210 + 90 for paddles
Total = 42,290
Add 1210 for dealer profit and your deal is at 43.5k.
If your dealer won't do that then PM me and I will recommend one that does.
Check the "what are you paying for your E92" sticky at the top of this forum section as well.
