Thanks for the welcome guys.

I think the car is probably quick enough for my wife, but it was that much fun I would have to get out in it every now and then.

Thanks dieselhead for the heads up on what to look for under the bonnet. This is the one we're looking at:

We'll see if they get back to us. It has a couple of light scratches from everyday usage, and a stone chip in the windscreen, but otherwise it's nice. The wheels look good on it too.
