Hi all, Newbie here, 1st post. I'm in the process of buying what appears to be a 70's terraplane. The top that's lifted to exit & enter the car appears different than others. The ones I've seen open lengthwise along the outside edge of the top. You'd then have to access on the cycle side. This one pivots forward with hinges on the front of the car, access is then by either side. Is this actually on some versions or is this car some sort of knock-off or copy of the terraplane. If it's not genuine, I'd have to rethink my buying this. Thx in advance for any help/advice received.
