I downloaded your VERY GOOD made Jaguar D and I have a few remarks while using this car in VR.
First I do have an purple edge around the windscreen.
The safety-belts and the jaguar emblem on the steering wheel are flat and do no show depth. I have seen cars that do have an 3d belt and emblem, so I hope you can fix that at the next update or remove it. If so than it will be a 4.5 star rating.
