};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.
Note: not all parameters have been reversed!

}CWeaponInfo
See List_of_Weapons_(GTA4) for the arrays referred to in the struct.
Array of CWeaponInfo's can be found at GTAIV.exe+0x1540A20 (1.0.7.0) and GTAIV.exe+0x124A600 (1.0.8.0).
