The 2003 Impreza WRX STI driven by Hammond in the show was a limited-run model known as the V-Limited edition. It was sold exclusively in Japan and is particularly intriguing to car enthusiasts.
This Impreza was initially painted a Subaru blue but during the special, the Grand Tour's trio were tasked with making modifications to their cars so they would be more fit for icy conditions. Hammond had his Subaru painted with a design from Martini Racing that matches the car's personality perfectly. Now, it just says 'Martin' as Jeremy Clarkson covered up the last 'i'.
Hammond isn't sure what he wants to do with the car yet. He could go full tuner on it, but he's also considering returning the rare variant back to stock.
As for the other cars that went along with the Subaru on the Arctic adventure, James May's Mitsubishi Lancer Evolution VIII was damaged so badly in a crash that the car is likely to be scrapped. Jeremy Clarkson's Audi RS4 isn't for sale, either. Another video reveals that Amazon, which produces The Grand Tour, is not about to take on any liability by selling an abused car to the public.
