First thing is pretty minor - before 5.0 you could double-click on garage on a map to return to it, now you have to press Enter. I'd like to see double click return, because it's just quicker lol
Second thing - i already made a thread on this, but i'll say it again - bring back the Khan 39 fuel tank capacity to 78L. Compensate it by increasing fuel consumption by x1.3-1.5 and that should be enough for it
