What's it worth? 87 cab

[Cattler]

Guys,

Son's about to start driving and my wife's starting to make sense about the impending increase in insurance costs and need for a third car he (and she) can actually drive...I'm the only one in the house who can drive stick. . I'm thinking about putting it up for sale and have the Excellence price range, but don't know what's really reasonable. Pics are in the "my garage" link through my profile. Here are some details: 87 911 cab, cassis red metallic n dents and paint's an 8/9, black top (previous owner replaced, I replaced right main bow and converted to manual), 140k miles (regularly serviced, no leaks, dealer replaced clutch per recall and updated from rubber center), Bilstein HDs all around upgraded from Boge, whale tail and front spoiler, fairly new tires (20k miles) on michelins, recent windshield with tint and antenna (5k miles), recovered sport seats with perforated leather (last year), rennline aluminum pedals with rubber grips, momo wheel with Porsche button, aftermarket radio w/ decent power, iPod connection, and alpine speakers, no a/c, cruise doesn't work. I'd definitely include the boot cover and might also include the tonneau cover (both black).

What do you think and what else should I include in terms of info in the listing?

Thanks,
Dave
