A conversion would be very expensive as well if its even possible it's nowhere near as easy as a civic I'm sure. But you will prolly spend at least half that trying to change it. Maybe more.

I'm trying to think of all the parts it would require. I'll start the list:

1) Manual transmission/clutch assembly
2) Clutch & Brake Pedal assembly
3) SSK?
4) Stick shift boot, nob and interior trim.
5) Possibly a new steering wheel

The brakes and hydraulic clutch share the same brake fluid on the MT so what is involved there? I'm sure there is coding involved as well. As everyone knows, the final drive ratio on the AT is shorter, but most MT drivers like the idea of swapping to the AT's 3.46 ratio for the added acceleration. Are the drive shafts compatible? What else to consider?

Garage List
The DME would likely have to change or be reprogrammed as well. This would not be a worthwhile endeavor by any means, either financially or the amount of effort required. Keep your car for awhile and trade it when you're not so upside-down.

Also make sure you really want a manual for the right reason and not just because people on these forums keep going on about awesome manuals are (me included,lol)

I love driving manual but its not worth the money to switch. It also has a lot of negatives because it sucks getting stuck in traffic.

Way better off trading it for a manual. Retrofitting a manual in an automatic in a BMW probably can be done by a seasoned veteran car craftsman with machining experience, etc. although it would be costly. And would you ever be able to re-sell it after? Most BMW typical buyers would run. Like someone already indicated, it's not a Civic.

6 grand to trade it in, is a LOT less than what it would likely cost to try and convert it

Not even worth considering, OP. Built up some equity and trade it out when your finances allow.

Don't use a dealer. Sell car private party, buy car private party. Of course a dealer will nail you on trade in.
