Here are requirements of cars suitable for tests
I would recommend choosing an instructor who isn't in it for the money and not just to get you through the test. I would try a few different driving schools and pick the best one for you and one that takes you beyond test standard including hazard perception and blind spot checking!! Sometimes a more expensive instructor and longer time taken is better then a cheap and fast way to learn.
I started learning in september 07 and passed in june 08 after failing once for a test where i felt i was not ready to be on the road on my own.
That what i did when i learnt and so far touch wood it has helped me not to crash into anyone. I also did my pass plus with my instructor.
