Be very carfull about part built or older part finished, some of the older cars were never designed with sva in mind and would not pass, also with some of the older cars that say registered as a classic no tax to pay, i looked at a cobra that was built in 1983 using a mark 2 jag as a donor for the running gear and registration number and used on the road covering 20,000 miles the v5 still said mark 2 jag the owner did not inform dvla of the changes so as not to pay road tax, under the new mot where the garage checks dvla computers for car information which would say jag and you turn up in a cobra they will not be able to mot the car no mot no road tax. you will be very lucky if dvla changes your v5 so you end up with a cobra worth nothing as it's not road worthy.
max.
