===CVehicleInfo===

The CVehicleInfo class holds all relevant vehicle parameters, as listed in the [[Handling.dat]] file. In essence the CVehicleInfo class is a representation of the data in the [[Handling.dat]] file.

The array of CVehicleInfo's is located at GTAIV.exe+11E3BF0 (1.0.7.0). (Note: unverified. The location might change between start-ups.). The order of elements in the array is exactly the same as in the [[Handling.dat]] file.
