That price does seem low if the car was really good condition. However the exchange rate isn't great for those of us in the UK at the moment so everything in the States seems expensive. Bit of a failing of the auction house though as I saw no marketing at all for it over here, that is unusual. Not sure what the situation is in Australia the other major RHD market. Historically RHD cars are worth less, there are less of them but of course the market is much smaller.
All the RHD cars were converted at the factory from LHD, thing like the LHD steering box mount were left in place so it wouldn't be too much of a job to convert one back.
