Not really a specific kit car question but I am sure this is the best section to ask this.

I basically want to take a pre-73 classic car, chop out all the interior structure and metal work and replace it with a full steel tube spaceframe. Widen the width of the bodyshell and a mild roof chop but not enough to loose the proportions of the car shape too much. Also the engine, transmission, suspension, steering and brakes would be replaced with more modern components from a different make of car.

In the end if all goes to plan I would have a car with retro looks but with modern sports car handling.

I would want to have a current MOT, tax it and let the insurance company know about the modifications with an engineers report, so not trying to cheat the system here.

How can I go about keeping the original log book to keep the original age related number plate? Do I just send off the log book and change the engine number and keep it at that? Or do I change the new engine number to match the engine number on the log book.

The closest example I can think of along the lines of my project are the z-car creations using a motorbike engine in a rear space frame built into a classic Mini shell. I see lots of guys keep the age related number plate so it must be able to be done without having to go through the SVA route and ending up with a 'Q' plate.

Someone must know the answer, so all advice gratefully recieved.

You are modifying the monocoque so a new VIN number will have to be allocated by DVLA.
The car will then have to pass IVA.
If you retain enough of the parts from the donor vehicle, on a points system, you will be allocated an age related plate.

However the way you describe the changes I doubt you will make enough points so a Q plate it would be.

Yes you can do this no problem, but you need to get the paperwork right before you strip the old car apart. You'll need to put the numberplate "on retention" with the DVLA and to do that it has to have a current MoT and I think roadtax. Then once the number plate's "frozen", strip the old car, buld your new one, presumably on a new chassis, and then the DVLA will transfer the number plate back to the new one.

If you go on the DVLA website there's a little bit about it but it's far easier to find your local DVLA and pop in and have a chat with them,. I did this in June re a kit car I'd bought but hadn't been regisatered and they were very helpful.

The car will still have the pass an IVA test and be allocated an age related plate prior to transferring the old one back though. If it's allocated a Q plate you can't change the registration.

Yes Mr2's right, you'll have to have the car IVA tested, a headache in itself, before you can register it since you're making substantial changes to the original design.

In order to keep your original reg number you've got to use most/all of the major components from the one donor car, so engine, gearbox, suspe4nsion etc. If you have a mix of engine/gearbox from one car, suspension from another etc, then you WILL get a Q plate whether you want it or not. As I said in my earlier reply have a look on the DVLA website, they explain the criteria for Q plates etc much better than I can here.

What you are proposing constitutes a "Radically Altered Vehicle". The rules on registration are here: http://www.direct.gov.uk/en/Motoring/BuyingAndSell...
It looks like you will have to pass IVA.

So, could he alter the chassis and body as he suggested, keep the original engine and suspension, get it through the IVA and then swap out the old components for new ones, or would he have to go through IVA again?

From the way i have just read your post the only way you can retain the reg is stick it on retention before you do any alterations to the car, because if you do what you have described, the the vehicle will be classed as radically altered with IVA needed and you will get a Q mark
