I remember this car being on sale 5 or so years ago on ebay, it was from the Kent area, and had rotten front wings and different wheels.... it was sold cheapish (5k iirc) for the time and then resurfaced for sale again, with the wings changed and the AMG replica's added which seems to have survived...
I think it would look better without the ductail.... They look better on the coupes/saloons and tend to spoil the lines of the cabriolet imo
