My budget is simply here in trade value, I really want a coupe, and I'm Colorado 80525.
I'd settle for another 540i to match the one I recently acquired, simply to have more diagnosis parts (that, and I'm pretty sure my wife is going to steal it from me). So far all attempts at contact with others I suspect might be willing to trade have lead to dead ends.
Somewhere between a coupe and a BMW 540i lives something called the BMW 6-series. Unfortunately BMW didn't make a 6-series during the time they built the 540i, so you'll have to go older or newer...of course I've picked something older. This 1977 BMW 630CSi is offered for $1900 in Ft Collins, CO via craigslist. It likely needs some work to get back on the road, but it seems like a good deal for the asking price.
What do you recommend for around $2200? Comments below.
