congratulations
i bet you must be over the moon and just as the summer heats up!
reading your post i take it that your rh was not registered when you bought it , that was a bit of a long time gap though between passing sva and getting your registration plates it would have driven me spare!
i was lucky i bought a car that was pre sva and was already correctly registered on a new v5 but it could have not been easy for you
hid you find having to check and then re do everything a pain, i certainly did
but when you take it on the road legally for the first time its the second best feeling in the world thats as long as you can relax and take your eyes off the warning lights, oil presure gauge, etc etc and that odd smell or knock that turned out to be nothing
