Thanks all for the good wishes and advice. I would also rather spend more on a decent car, than buy a bargain which proves to be anything but...
I don't think silver suits the car; she's looking for a dark blue car ideally - big GT is exactly the sort of thing that works for her too, rather than a harder, more adrenaline inducing machine. There's no rush to buy the first thing that comes along, particularly as there are 6 cars at home at the moment, mostly because the DVLA haven't managed to return V5s to us after 9 weeks. Not impressed.
