Ok so in the summer of 2006 I bought a Cannondale Rush 800...I have ridden a grand total of 7 times since then.

Time to face facts...I am a roadie and this thing is just hanging in the garage collecting dust. Priorities are changing and my cycling time is only going to lessen so I am going to sell the Rush. But what is it worth? I listed it on my local Craigslist for $1400 knowing (I think) that it is a little high.
For those that want them here are the specs:
Frame Rush, 110 mm
Fork Lefty Speed Bonded DLR2, 110 mm
Rear Shock FOX Float R
Rims Mavic XM117 Disc, 32 hole
Hubs Cannondale Lefty front, Shimano M475 rear
Spokes DT Swiss Champion
Tires IRC Serac XC, 26 x 2.1"
Crank FSA V-Drive MegaExo, 22/32/44
Chain Shimano 9-speed
Rear Cogs SRAM PG-950, 11-34
Bottom Bracket FSA V-Drive MegaExo
Front Derailleur Shimano LX
Rear Derailleur Shimano XT
Shifters Shimano LX Dual Control
Handlebars FSA XC-281AOS, 25 mm rise
Stem Cannondale XC3 HeadShok, 31.8 mm
Headset Cannondale HeadShok Si
Brakeset Shimano LX
Brakelevers Shimano LX Dual Control
Saddle Specialized Rival
Seat Post FSA FR-270
I have also added a bash guard but still have the new large ring. Shock pump will go with it as well as a Specialized Turbo 2 computer and the required Lefty computer mount.
So hardly ridden Rush with Lefty is worth?
