Here it is - spotted on Italian Ebay - your own 1:18 scale Guzzi dream garage or mini dealership, depending on how you see it. Yours for just 270 euro!! He can also build you a bespoke 1:18 scale garage with your preferred auto, or any other type of workshop. My small unit feels like it's 1:18 scale most days. Good luck to the bloke - I respect entrepreneurism of all types and especially in miniature.
