How to buy one's first vehicle

[killerkebab]

As title really. I am currently learning how to drive and thought I could get a car when and if I pass, but I am frankly a bit useless. I can't get lessons very often nor very regularly which means I don't progress very fast, and have realised I could probably use a car to practice in as well as to drive in if I ever get a license.

The problem is I know just about nothing on cars. That is, I have no technical knowledge. I know roughly what to look for, but I don't know what car is better than the next for a total beginner, let alone who to get to insure the car nor anything I need to be on the lookout for. Hell I don't even know whether I should get one now to practice on or get one if I pass.

I'm assuming a lot (if not all) of you drive and thus you have all had a first car and you can all tell me about how you went about it and how I can end up with a great car to make me a great driver (hopefully)
