Scaleform displays a car stats display. There are actually 20 of them so you can use MP_CAR_STATS_01 to MP_CAR_STATS_20 to display more than one!

BeginScaleformMovieMethod(scaleform, "SET_VEHICLE_INFOR_AND_STATS")
PushScaleformMovieMethodParameterString("Vacca") -- show the vehicle name
PushScaleformMovieMethodParameterString("Tracked and Registered") -- show the vehicle description if SET_PLAYER_NAME and / or SET_CREW_NAME are not set!
