btw... according to your text you are want the player to click onto the vehicle to select it eh?..
MSGBOX only shows a box with text..
use DIALOG_STYLE_LIST ^^

edit: oh and I guess this won't work out too well 'cause as far as I know the dialogs have limited lines (even the lists) and using all vehicles seems a bit too much lines to me..
may I suggest that you use another dialog to select the vehicle type and seperate them into types? like sports cars, etc..
