I'm Thinking of selling my R53 Mini and wanted to get an idea on what I should sell it for?

M7 Cold air intake
17% supercharger pulley
2% ATI Harmonic Balancer
Shark tuner
M7 oil catch can
Borla R Cat back exhaust

Meghan Racing Coil over suspension(lowered 1 inch and aligned properly, front and back)
M7 Strut Tower brace

Car runs strong and handles real good for a street car.

I have had the car for about 10 years and have never driven it in the winter.
Interior is in decent condition for the age.
Exterior is in decent condition, couple minor things but nothing major, no rust whatsoever on the body.
Color is Dark Grey
car has about 135,000 miles

Recent Maintenance:

New alternator
break job, all 4 wheels
right front wheel speed sensor
Rear oxygen sensor

Included with the car will be:
2 complete sets of rims
spare supercharger(good core)
spare stock intake
and a few other miscellaneous items.

Car has almost new Bridgestone Pole Position 2 tires.

Car is located in South Hadley Massachusetts if anyone is interested in looking at it.
