...vanquish from barely working paddle gearbox, to regular 6 speed?
good question. Not that im going to get one soon, but i have always wondered about the cost involved.
Call Tom at Autosport Design in NY. He may actually have one in inventory that was converted by the factory's 'Works' program. Or at least he would know how much it costs to have done.
Tom is the US expert - he's had 5-6 manuals for sale over the last year that were all done by Aston Works Service at his shop some years before. There was also an article in last month's Classic Car about doing the conversion to a Vanquish. It runs about $22k USD for a pre-2005 car and closer to $30k for an S since they update the dash to the 06 design. I have talked to him a couple of times about it and they will take names for future conversions. If they get a few people signed up at a time then it becomes cost-possible to bring Works service back across the pond.
