Back then it was $20, now $30? Also it used to go on sale for almost less than $10! I only reccommend to get it if you like the mustang's preformance, Its got really good speed, average turning for the tier(IV), and it has x6 .50 cal which means it has ALOT of ammo. But what makes up for these is the reward 100% +100% on lions, 232% more on research, this might seem like alot but the fact that the grind on this game is INSANE I do NOT recommend it at all. The P-51 has some really major setbacks, it has x6 .50cals meaning its decent for ground units and awesome AP rounds, but, its up against 20mm~30mms and at high speeds (330mph/650kph) the wing tears off due to G-forces, I have many tier IV's in all countries but never have I seen a plane that tears a wing so fast at these speeds. It is able to carry 2x1000lb bombs, 6 HAVR rockets, and 10 M10 bazooka rockets very impressive due to the fact that it is a fighter. Also, you will be up against tier IV in other countries meaning most other planes will out preform (Russians...) not only you but your teammates. So all in all SAVE YOUR MONEY unless you want a shiney mustang that is fast and prideful. NOTE: what i recommend is to find a plane that your good with, tier 3-4, grab a talisman for it, its MUCH cheaper and it gives 100% to research but the price depends on what you are flying(ex. swordfish mk.1=350GE, Ta 152=1350GE).
