I put my 135i (N54) up for sale last week.
I would prefer to sell at the parts locally here in the midwest since I'm able to deliver them (within a reasonable distance). This way you can see the quality of what you're getting.
I'm in the Indianapolis, Indiana area

the car is also for sale on auto trader and most of the major BMW sites
Thanks for any help
