well the obvious things you need to do is:
1: smooth the outward curving tail light panel on the back of the car.
2: add the 'black outs' on the nose in front of the closed headlights, I have heard people either scratching the shape into the body and then repainting it, or an easier method is clear decals cut to the correct shape and applied to the nose of the car.
3: make the fog lamps (even that stupid orange one) not flush
as the body is mostly metal that kind of work can be hard unless you have proper power tools for the grinding/sanding
the EASY stuff you can do that will make a WORLD of difference is:
1: remove the clutch pedal from the dashboard (far left pedal)
2: paint the rear cargo area 'carpet' tan instead of black, for some reason the back side of the rear seat and everything behind and to the sides of it are black instead of tan.
3: use a black wash (blend of paint and thinner to water down the black paint) on the recessed areas on the rims that are all silver
4: (this could be tough unless you have a good printer) get a better 'KNIGHT' plate on the back of the car, the color is off and the font on the letter I in KNIGHT is incorrect. here is a good 'replacement plate, just reduce to proper scale and print, apply a piece of scotch tape over it for that 'glossy' look.
if you have any questions feel free to ask me
