This car is far from a kunos-standard car for many reasons, mainly due to it being far from pipeline-standard. (Pipeline is the kunos base "guidelines" so to speak when making a mod.)
The car has a horrible model with topology that is rather weak in certain places, resulting in sections of the model which are obviously weird, which, for example, you can see with the weird reflections.
The physics are very unrealistic indeed and do not handle like this type of car should. The car should have physics based on real data from the car, however it doesn't, resulting in a poor driving experience that is in no way in comparison to how the real car would handle.
This, in addition to all the random CSP stuff that has been added seemingly in a higher priority than the car actually being pipeline-standard, results in the car being very poor quality. Do not waste your time with this one, as it is in dire need of an update to fix the issues mentioned previously and more.
