Well, sooner or later it was bound to happen. As soon as I knew my wife and I were expecting a baby, I figured at some point I'd have to broach the topic of selling a car. The family fleet has reached a possibly unsustainably high count of four cars, so we're evaluation all the options.

I'm trying to do all the usual searches, but these cars just don't trade in enough volume to get an accurate idea of their value. So what do you think its worth?

2002 Z3 3.0 Coupe, 5spd
Black Sapphire Metallic ext, Dream Red int
~70k miles

Almost completely stock except for Besian D-VANOS fix, upgraded water pump, MZ3 shifter, ZHP knob, and a well-matched aftermarket stereo with Bluetooth, ipod, etc.

Paid ~$21k for it as a CPO about 4-5 years ago.

Not very enthusiastic about selling, but the rest of the fleet is looking non-negotiable to sell and keeping a fourth car just for the occasional weekend drive is looking iffy. Daily delivery of the munchkin to daycare falls to me and baby seat + airbag is a no-no, so selling my Subaru and keeping the Z3 would mean daily-driving a 12mpg van. :(
