congratulations Cem! I expect you will love it. Just think of all the cool jackets and hats you'l need up north. Get safety glasses, prescription if you use one.
...I have never driven a right hand car, with sequential gear box. ...
I can't speak to the gearbox, but I do have the steering wheel on the proper side too. Should be no sweat adapting to where you sit in relation to the car, as long as you have always aimed at the center of your line. Only ONE caution. Left turns. If you cannot see due to big thing in the opposite lane, DON'T GO. As everyone has converted to P/Us and SUVs, this has become a very common accident. People get impatient and pull out, even though they can't see, and BAM, KAPOW, etc. Otherwise, RHD is joy. It lets people know that it is a proper British car. God save the queen.
