Whew, a lot of nice Minneapolis Craigslist deals in the $1000 range.

What size? 52 to 54?

2010 Cannandale Synapse Carbon 5, 54cm - $1000 (New Brighton)
Trek Madone SL 5.2 - 54cm Carbon w/ Ultegra Components - $1000 (Minnetonka)
2011 Trek Madone 3.1 Carbon 52cm - MINT!! - $900 (White Bear Lake)
Scott CR1 Carbon Road Bike - $900 (Minneapolis)
54cm Motobecane Le Champion CF - $800
Orbea Onix 51 cm, full carbon - $950 (Minneapolis, Longfellow)
trek madone - $1100 (mpls)

Ok, so this one is a Cross bike with an aluminum frame, but still worth considering.
2015 Trek Crossrip Elite - $850 (Chaska)

It is hard to say which one I'd choose. Maybe narrow down the sizes a bit more???
