I appreciate that this is a picture taken during development, but it's the only profile picture of the 'new' sammio I could find -
Personally, I wouldn't base a car of this type on a Spitfire tub. The wheelbase is that bit too short and the Spitfire bulkhead too high, resulting in a car that might just look short and dumpy.
To me, the original (Italian) Sammio Spyder got the proportions just right and the Herald/Vitesse wheelbase allows for a full-sized driver (me, Barry, Phil J etc., all about 6' tall and harumphteen stone) to actually fit behind the wheel.
Can't see much difference in the front overhang between the above and below either.
Dash is a moulding taken from a Porsche 550 that I chopped about and blended in. Works really well and suits the car imho.
