Hi all.

I've been lurking here for a while and have decided to show myself at last :-)

I'm been considering building my own car for some time now and have finally started to put mouse to screen (or whatever the computer equivilent of pen to paper is ;-)) and have started to design my mean machine. This process has brought up loads of questions, most of which i'm sure i'll find the answers for eventually (and thats half the fun!). However, I do have some questions about registration etc.

I'm planning on building my own chassis / suspension etc myself from the ground up but using various bits and pieces from existing designs. I know that if you use parts from several cars it will result in a Q registration, but what if those parts are purchased seperatly from a vehicle? and what if the parts are reconditioned before purchase (or after)? I guess this point applies to the engine / gearbox as well.

I've done the ususal searches etc but seem to come up with confilcting info and it also seems to be biased towards the donor car scenario rather than the parts purchase route I have planned.

Also, does anyone know of any free software, someone or a company that can do stress analysis of a chassis etc from a CAD drawing?

Thanks for any help.

Jeff.

I got a Q plate for my Tiger, but it could have had a non-Q I think if I'd had any V5/logbook from any one of the donor cars, or at least that's what the DVLA person said at the time.

It has VW Golf front uprights, a Cortina rear axle and a Mondeo engine, so no two parts from any one car, but the DVLA didn't seem to care.

Of course things seem to vary dramatically depending upon which DVLA branch do the inspection, they don't seem to have any solid country-wide practice.

I was having a conversation with someone only a couple of days ago, who basically said look for anyone at a DVLA office that could recognise a component of a car, they'll be the ones trying to register...

Basically he was saying no matter what the regs say, the staff at DVLA wouldn't recognise the difference between a Cortina rear axle and a jag IRS, just tell them what they want to hear and wave an appropriately coloured piece of paper under their noses!

No idea how accurate his take on the situation is, but I don't find it that hard to believe.

You only need two "major components" (from the DVLA's list) off a single donor to get an age-related plate of the same age as the donor. That should be pretty easy - unless you're thinking of building your own engine / transmission / steering / axles...! Just keep the V5 of the donor you've chosen. When you come to register the car, you will get a built-up vehicle inspection form asking where all the major component came from. Just say that the body / chassis are new (your own fabrication), pick whatever two major components you've chosen and quote the donor's registration against those two and put whatever you like against the rest.

...Well, that's how it SHOULD work anyway! The trouble is, many DVLA offices tend to make the rules up as they go along!

The examiner at my DVLA inspection didn't have a really good look at any of the components, apart from checking the engine and chassis numbers, so I could have put anything on the build-up form and I don't think they would have noticed. I don't think she would have known what vehicle the uprights and steering came from, or the rear axle.

As it was I didn't care about a Q-plate or not, so I put down what was actually on the car for simplicity and speed as I was expecting to have to battle with them over not supplying detailed receipts and a log-book - all I had was a single receipt for the kit itself which included all the donor parts, and a receipt for the propshaft. In the end though the examination only took about 10 minutes with no questions or problems of any kind.

It depends on the branch and examiner you get I think, not on what their quidelines and documents say. You could try and get your appointment last thing before lunch or just before the examiner's clocking-off time, might make things quicker and easier smile
