here are the comparison pic between the gtr specv and the gtr from the 5 gtr cars boxset.
from the naked eye, there's not much significant differences. probably the most significant differences is at the wheels. The rest are just very minor. here are the differences that i manage to spot:
1. specv colour is a little bit (just a little bit) brownish compare to the normal gtr (black). Maybe 5% brown + 95% black compare to the 100% black of normal gtr.
2. specv tail light below the spoiler is painted with red. normal version is just black.
3. specv exhaust area is painted with silver. normal version is not.
4. specv spoiler is printed with carbon fiber texture patern, normal version is not.
5. specv windscreen is more transparent than the normal version. normal version wind screen is a little bit darker.
