I don't know about tolerances but it is a viable argument. What I do know is that almost all of your super-cars are built using some form of composite material, Carbon Fiber and Kevlar being the two big ones. These material extremely mold-able but also prohibitively expensive when it comes to mass produced cars.

Why can't they be made of fiberglass like Corvettes?

It's still more labor intensive. You can stamp metal, any kind of composite has to be laid in a mold in several steps and then infused with resin (the resin is a big part of the cost). Further one the part is finished it has to be trimmed out usually with grinders and sanders. Even with fiberglass the cost of production is going to be higher than the equivalent steel, aluminum or plastic part.
