The company might come with the decision to increase the DBS production if they want to keep they customers happy. Everyone waiting in line for a DBS is a VIP and a five year wait could cause all but the most die-hard Aston fans to consider another car that is available right now.
As you know, Aston Martin is also working on the four-door Rapide to compete with the Panamera. Initially Aston Martin announced that they will produce 1000-2000 units a year, but with such strong demand for the DBS, they might be forced to outsource the Rapide’s production.
