I was thinking about newcomers to game and have an idea to add some sort of vendor or low icon reward with green part set at max lvl so new players can get high rank vehicles easier (almost as we all know what green parts are worth), at let's say icon:
20 - SR,
30 - HC,
40-DG,
50-TC,
60-DF,
70-TC,
80-RR,
90-RX,
110-AR,
120-HX(hovercraft not sure short version),
130-MT,
140-AB,etc
