I'm not so sure.
The MacLaren knock-off has a narrow windshield on a body that makes the Porsche RSK Spyder next to it look tall, single side windows, and a pronounced dip in the line from the top of the front wheelwell to the rear.
The body in question has six side windows set flush with no rubber gasket and all straight edges. The windshield is quite wide, with a lot of taper to the cabin. You can see the right lower corner of the windshield is above the last number on the license plate. The body is probably aluminum {note the reflections in the lower door area) and is mostly simple curved with some crown in the top and above the front and rear wheels.
The plan taper abaft the rear wheels is as pronounced as the problematic area seen in the profile view.
