Mashallah! congratulations on the new ride.
Car desperately needs a detailing session. Please sort that out at the earliest.
Everyone has their own liking when it comes to body modifications. I would suggest that you keep the car neat and clean (stay away from decals and the lot). A clean and simple car appears more attractive.
Try to get your hands on original MazdaSpeed body kits. They would give the ride a much more aggressive appearance (if that is what your target is).
Also I hope you are aware of how to care for a rotary engine. Have seen too many rotaries parked due to lack of care/maintenance.
