Both the coupe and hatchback are curved tempered glass. If you've checked the prices on new glass you wouldn't complain about $100. for a used one. Lexan isn't legal for street use in any state, plus lexan doesn't stand up to weather and sun well, turns opaque in a few years. That doesn't matter to you being as it's only a side window, but it's a sure giveaway that it's not glass. If you wanted to go with the lexan, you can by a sheet big enough to cut you own for about $50.00, cut it with a very fine tooth jig saw, it's flexible enough to bend to the curves you need.
