What Car Should I Buy?

Indeed, it's been 3 years since I passed my test and last drove a car. Since riding around in London my observation has gotten much better as a result, and i'm fairly sure i'll remember what all the pedals do when I get back in a car next.

My car sat in Oz doing the opposite of rusting (fading in the heat?) for 5 years. I didn't drive at all while here but arriving back home got in a drove it - it's like riding a bike (trackstanding in a car is easier too). Buying a car just to have one, especially in of all places London, is a bit daft.
