MAVERICK--- Most of the key points have already been made. Clean it up (including engine bay & change the oil), don't make any more mods (no new stereo), and definately market it on the web (AutoTrader.com, Vehix.com, Cars.com, etc).
Don't be afraid to sell it to a long distance internet buyer. Just be damn sure and use "ESCROW.COM" as the conduit to complete the transaction (the "buyer" pays all fees for ESCROW.COM and D.A.S. shipping/transport). You may be asked to drop it off at a nearby authorized D.A.S. terminal for shipment/transport. Remember, you're not looking for 100 buyers; you're only looking for 1 (he/she "IS" definately out there somewhere).
With your racing hobbies and lifestyle; then you're right, a used Van-nose type Camper RV with a heavy-duty trailer hitch would be perfect for you. Put a couple of Mountain Bicycles (for riding around camp) on the Van's front bumper and you're set. Keep your $500 "beater" for commuting to work. My "beater" commuter car is a 1980 Ford Fiesta that gets 41 MPG. Sweeeeeet!!!
MARLIN--- I think I hear Carrie Underwood's new hit song playing just for you..........................
