Sure seems high priced compared to what it might sell for here in same condition as a LHD, my guess around $3000, which would be about half their asking. A quick review of December MGE and what was available:
1966 MGBGT easy restore L1100
1973 MGB with overdrive,excellent L4995
1979 MGB V8 chrme bumper conversion L8995
and my dream MG: 2005 ZT260SE V8 20,000 miles, L9750
