This immaculate 1967 Ford Mustang Fastback is estimated to sell at British auction for $95K. It’s hard not to whisper Steve McQueen’s name when presented with a Ford Mustang 390 GT Fastback, even if it isn't a 1968 model. The American classifieds may provide evidence of eye-watering sums being traded for healthy Fastback specimens, but it’s not always the case in Great Britain.
