I'm afraid I don't know any more about these two particular cars.
Pic no 17 was taken in the Paddock, the car looked like it was being prepared for racing so I presume it was real.
Pic 28, I didn't have that close a look at. I'm not a conoisseur of older Ferraris but I tried to capture pics of all the models there rather than just taking pics of my favourites.
Certain cars were awkward to photograph as there were constantly people crowding around them.
Pic 28 has an expensive private registration number on it so I would doubt its a kit car but who knows!
The Enzo was in the indoor display area along with an F50 & F40. I only saw one other F40 which was a LHD one you can just see driving up a hill in pic 8. There were plenty of the more "common" modern stuff, 360, 355, 348, 308, 550, Testarossa, Mondial, a few dinos etc etc ... all in all a very interesting day and as an added bonus only 20 mins from my house!
If the weather stays nice I'll be taking mine to work for the first time tomorrow and will get some proper photos. Hopefully if its sunny my boss will have his new 575M with him too so I can get piccies of that too.
