You are acessing a negative array index.

Check your GetVehicleNameFromModel function.

Re: Run time error 4: "Array index out of bounds" - Jefff - 21.05.2014

Check Vehicle[v][owner] in strcmp because if Vehicle[v][owner] is empty strcmp match

pawn Code:

stock GetVehicleNameFromModel(modelid)
{
    new vn[50];
    format(vn,sizeof(vn),"%s",VehicleName[modelid-400]);
    return vn;
}

    if(!count) return SendClientError(playerid, "You currently do not own any vehicles");
    return ShowPlayerDialog(playerid, 2, DIALOG_STYLE_LIST, takecarr, Lrg, "Take", "Cancel");
}

and you don't need format here

pawn Code:

stock GetVehicleNameFromModel(modelid)
    return VehicleName[modelid-400];
