is it possible to use a tax exempt donor?
i have a really rotton triumph herald with a really sweet engine and overdriver g/box.

how much of the car do i have to use to make my locost tax exempt as well?

My understanding of the current regs is that the only way is for you to restore the Triumph. If you use it as a donor the date of first registration for the new car will be the date it goes on the road and so will not qualify for tax exemption.

I've been down this route.

You'll get an 'age related' plate, but no tax exemption. I used a '68 Mk2 Cortina.

Cheers,

carnt you use the chassis and make a body tub to suit ?

i know its not the lightest of car but many have been done

No - you may be able to get an age-related reg if you use enough parts, but the only way to keep the original tax-exempt status is to use the original chassis

You need a minimum of 8 pints to retain the old reg.

Chassis
Both axles
steering
Suspension
Transmission

ought to be enough.

I have this problems with an old land rover I rebuilt (into a coil sprung jobbie).

Why not use the chassis etc and rebody it to look like a Lotus 7 style car.

With a chassis derived car, the bodywork does not count for the points system. only the chassis.
With a monocoque car (modern car with no chassis) its the body that is the chassis, and you loose out if you rebody it.
On the points system a Chassis is 5 of your 8 points.

Have a look on the DVLA wesite on rebuilt and radically altered vehicles. It explains it all there.

Using it as a donor will get you age related, but not Tax free as it wasnt "Built" before Jan 1st 1973.

You need a minimum of 8 pints to retain the old reg.

is this to bribe the DVLA

If I had 8 pints I'd probably throw up

after 8 pints the herald could look like a seven
