IF the car was sold as quickly as the OP suggests and for the asking price too, that suggests to me it was underpriced.
With better promotion and more viewers/prospects from here, there could realistically have been a bidding war and the sale price could've been massive!
Instead of being pleased with a quick sale, I would be gutted I'd just missed out on hundreds of pounds.
Unreal Master Tech is certainly not an unreal master salesman!
