Looks as though the brilliant idea for the track will not fly in my existing facility because of the parking issue. I am still interested in doing this but need to watch for a great deal on a building that has the parking.

I'd love to help with a track in SoCounty!! There are no facilities down here--and I TOO believe you would be able to pull as far south as SD for a nice indoor facility. If your really serious--I don't think you could go wrong with a facility like Westcoast in La Mirada. Danny has done his homework--and the onroad asphalt works really well.
The dirt track is made out of clay--instead of just dirt--and that allows water to be held really well with nearly NO dust kicked up to ruin the onroad track.
The curbs on the onroad track work VERY well also--so you should note that as well. I'm sure you could get the same asphalt company to lay your surface down-- then it's up to stocking the hobby shop side of the business with enough parts to keep the regulars in tires /batteries and car parts.
FWIW

Your right it's about finding the right building at cheap price at this point with the parking. I'm still looking.

What size building are you looking for? What kind of rent would you like to pay?? I've been finding buildings available around 50 to 65 cents --and I'm looking for small warehouses--under 3000 feet. But over 5000 prices get a little more flexible also.
In the Orange area-- cheapest---I DID find some warehousing over in the Tustin area off Jamboree and the 5 fwy. at .45 foot--they wouldn't let me store cars there--but a track--maybe?? I'll call and find out once I know what size your' looking for.
