VA Beach has a million potential customers, though, a lot of whom are active duty (steady jobs!).
Even though Buckingham is close to Oak Ridge/Shoe Creek/Big Levels, can you afford the overhead with a much smaller list of potential clients?
I've been in C'ville for about 9 months, and aside from Brown's Jeep (dealer), I don't know of any 4x4 shops here! Is it worth the hour drive up here to run a business? I'm just thinking out loud, here, but I personally would love to have a good shop. Most people that come out to Nelson County from Richmond/Tidewater go through Charlottesville (64W to 29S), or they take 60W from Chesterfield/Powhatan.
