...I would look to the 40 for nostalgia...It would definitely find itself to car gatherings, but MOSTLY Sunday drives along the Blue Ridge Parkway...I have no idea what (driving one) would feel like.
From what I can gather after reading the above, it appears to me the way the car "feels" when sitting behind the wheel
might only be a secondary consideration for you? Apparently, you're not going to be taking it on long trips...'not going to be taking it to the track, etc, etc? If that's the case, I wouldn't think how the car feels when "driving" it should really matter 'cause you're not going to be 'pushing' the car anywhere close to its limits anyway, nor are you likely to be IN IT for hours at a time, right?
I have driven a Pantera (on surface streets and on the highway)...'owned/driven "(60/70s) Corvettes"...'owned/driven a 2006 Ford GT and 'ridden in a GT40 MKII - "AT SPEED(!!)"if you get my drift! 'Also
drove a MK I for a VERY short distance on a private road at ho-hum speeds. From a
driving standpoint, the only
big difference I noticed with the MK I was its steering felt a bit 'heavy' at slow speeds (no power steering) compared to the other cars I've driven/owned. Yeah, as with all cars, there are pedal feel/off center location differences, shifting differences, brake feel differences - that sort of thing. You've ridden in a friend's GT40, so you already know they're noisy, they aren't very comfortable, they're cramped, their 'ride' is...uh...'firm'...aaaaand they can be a bit 'spooky' in traffic! In short, they look, feel, and drive like a race car rather than a 'road car'. ;-)
Does the Superformance attract more money because it is a factory built car?
I would think, assuming they do tend to garner a bit more price-wise, that's because they're Shelby-blessed and they're the closest thing to an actual 'original' compared to the other offerings out there...mass production-based, anyway.
All the above JMPO. OMV.
