Grab it before it suddenly reach EOL similar to FM3 and FM4.

Besides Rally expansion, the season pass include car pack which help to unlock several 1000 club achievement as well.

Should similar to FM4, even with season pass you still need to download the car pack in-game otherwise once it removed all DLC you still can’t grab the car pack if you DIDN"T download once.

do you know if it will be on sale again? i want to get the rally expansion but i don’t think it’s worth 20 after so many years. The game itself costs less than the expansion
