Am after a bit of advice really.

Am currently re-shelling my Sapph cosworth in a 3dr shell, unfortunately i can not afford a genuine 3dr shell (kids and house cost too much!) so i got a 1.3 shell with no rot. Have only used the shell itself all other parts are geniume ford!!

I have now 2 choices register the car as a Q plate cosworth or have it as a modified 1.3 on the log book, my question is this really:

A) If i register the car on a Q plate as a re-shelled cosworth can i still join clubs like RSOC as a cosworth owner, as you have to supply Vin details etc dont you, is the car on a Q plate still classed as a cosworth?, i believe the logbook would still say RS Cosworth on it.

B) If i leave it on its 1.3 reg and class it as a "modified" car can i still join clubs as above?

Obviously i own a genuine cosworth at the moment but its shell is past repair and i dont want to go back to a sapph, i fancy something different but will be gutted if by using simply the basic shell and keeping everything (and i mean everything) else cosworth i wouldnt be classed as a cosworth owner anymore!! I enjoy my RS owner status and am proud to be an owner!!!
