The date of registration relates to the chassis number although you can replace the chassis ans keep the registration along with the date old reg as long as the chassis number from the original chassis is not used again. (this would be cloning a vehicle)
Changing anything but the chassis will have no relevance with regards to the number plate or date of registration.
When you change the chassis the DVLA will probably want to inspect the vehicle if you want to correct the logbook. (A receipt for the chassis is a good thing to keep)
That is the same as I see it! As long as the old one has the plates transfered and preferably cut up there should be no problem.
When you say to correct the logbook what do you mean?
I would class this as a rebuild and thus not been liable for SVA. (assuming all the old servicable parts are used)
If you mean to correct the milage back to zero then surely all the drive train and engine would need to be overhauled and proof of such. And then they would probably give it a new 10 plate and no tax exempt?
Surely if your after keeping the tax exempt status your best to...
Strip it, swop chassis and plates/id, cut old one to bits, and rebuild.
That way it would be the same age, millage, and id just it would have been overhauled and have a newer chassis.
I think DVLA would only need to be involved if you were wanting to claim the car as overhauled and NEW?
I am not saying that you may not want to SVA it (not sure if you can just ask for one without it been recorded by dvla, you could have an insurance sign off guy look at it and give you a report to say its all ok).
I would surgest a new MOT at the least!
I mean if I were to take my car apart for the hell of it and put it back together there is nothing to govern that except when it goes for an MOT and I find the big bag of spare nut, bolts and things! were in fact required!:doh::doh::doh:
