I'm in a bit of a dilemma here.

I have a chance to have a trans swap done in my E34. The automatic has a questionable amount of miles left in it and I hate the thing anyways.

My E34 needs a new rear bumper (I have an M5 one waiting for paint) and a hood that's dented. Also needs door brake.

I was considering going with an E39 because of the luxury. I hate to say it, but I do like the E39 better.

I do know that the e39 will cost lots more to run.

But: I'd have a $150/mo. car payment on it for 30 months. 110k mile '97 540i6 that has all problems but cooling system and clutch addressed.

For the E34 I have ready to install:
Hella Euro Smiley headlights
6000k HIDs
Euro trim
E34 M5 rear bumper
Bent Style 19s that I need straightened (for winter)

which won't go in if I do the E39.

What say you? Cheap, timeless E34 525iM with no payments or a black/black 540i6, a musclecar in a tuxedo but would put a bit of strain on the finances.
