If its very overpriced and very underpowered then that's a start , lol.
All joking aside , 'Supersport' should be on the v5 I assume , alla Lotus , RS , Cosworth special models .
And being a later ford model the vin must be STAMPED into the chassis somewhere which should match said v5 .
I would take a very close look there first if it was me .
Good luck.
