Erik_S & Zinni, thanks. Yeah I need some work on the headlight cover. For the wheelarch, please see a view from the rear, I think the car is supposed to be that way. But I could be wrong, too
Silent][Moebius, thanks for pointing out them. I will check them later. I've changed the floorplane colour. About the glass, it's not too thick, because it have not yet any thickness

I need some work on making real-looking glass, with real IOR and a realistic thickness (let's say, 2mm)
Here's an update : rims, tires (just placeholders for now), rearshield, and some tweaks.
