You need deep pockets to run an Aston Martin. Very high maintenance. A friend ran Peter Crouch's old DB9 as his daily runner for a few years. But I'd get a Jaguar XF instead, or even an XK if buying 2nd hand. My favourite XK was the 5.0 V8 roadster, not the XKR. If you go for an XF, remember there is hardly any luggage space in the roadster.
