Dont think you could do that as the car wouldnt tally with its registration document. SVA testers use a model report to check that the vehicle being tested is what has already been fully tested by a testing house -if it tallys with the model report then they just do a simpler test(emissions,lights etc).
The only other option is for someone to get a manual Altezza fully tested and get their own model report drawn up- costs in excess of £5000 (and more if its crash tested!!!). They could then get their money back by renting the report out at say £300 a go whenever anyone wanted a manual Altezza ESVA tested.
