These are the ingredients for the Aston Martin Vantage GT12 Roadster. Take One regular Vantage GT12 and mix a little Q by Aston Martin into a bowl and the put the whole thing into a oven at around the hotter end of the temperature settings and you end up with a one off Vantage GT12 minus the roof. The Vantage GT12 Roadster is based on the limited edition Vantage GT12 coupe which is directly derived from Aston’s GT3 endurance car so that means its the most powerful Vantage in the model range. That also means you get a 6.0-litre  V12 powerplant that fires 592bhp, a 100kg reduction in weight and heavily revised suspension to bind the car even closer to the road. You also get that GT3 endurance racer look and things things like Magnesium inlet manifolds with revised geometry, a lightweight magnesium torque tube and a full titanium exhaust system with centre outlets. The interior is also revised, the centre stack is made from carbon fibre as are the sports seats and it’s all trimmed in Alcantara. Going for the air-in-your-hair experience means the Vantage GT12 Roadster looses the rear plastic window and a bit of drama because the GT12 Coupe’s massive rear wing is gone in favour of bespoke, for-the-customer-requirement, aesthetics. Only 100 Vantage GT12s were ever made and for one customer that exclusivity was not enough so he asked Aston Martin’s bespoke customer/personalisation division, Q by Aston Martin to make it more exclusive. So here is the end result, a one-of a kind Vantage GT12 Roadster, a special commission that Aston Martin is able to cater for thanks to their Q personalisation service and a high net worth customer who has very deep pockets. What this Aston Martin Vantage GT12 Roadster is designed to do is advertise Aston Martin’s bespoke Q service. The Q service is fast becoming a nice little earner for Aston Martin and it means owners no longer have to go to the local chop-shop in a run down Dagenham industrial estate to get after market looks. It also shows that Aston Martin’s clients have a bit of money to spend, the regular GT12 costs £250,000. You should add at least another £200,000 on top of that for this heavily revised limited-limited bespoke revisions. Special commission’s don’t come cheap especially if you go direct to the manufacture’s special operations team and Aston will charge you extra because they can and because customers want the job done properly.
