For now the only one that really works is to open the hidden custom auto show.
Like in Forza Horizon 4 (it's exactly the same method)
Steam and Microsoft versions only (offline)
First: turn off your antivirus (Windows Defender or others)
Launch Forza Horizon 5 in windowed mode
turn off your network
lauch cheat engine 7.3 or newer
link the game on cheat engine (processes)
in Forza Horizon 5 go front off the auto show (front of)
in cheat engine setting value type on: String
and copy / past: AvailableInAutoshow= in cheat engine scan bar
run scan
as a result we have 3 values
modify the bottom value and change:
AvailableInAutoshow=
with
AvailableInAutoshow=1
ok to valid
in game now we have open the hidden custom auto show we can enter in
we can buy vehicules and will insta-selling them in the auction we'll have restart network
When we have buy all vehicules we need.
in Cheat Engine modify
AvailableInAutoshow=1
on
AvailableInAutoshow=0
close cheat engine
restart the network
in game
enjoy your vehicules value in auction
(for exemple (if you begining in FH5)
you can buy a Delorean for 15 000CR
it's insta sell in auction for more of 30 000CR)
be carefoul not all vehicules are interesting
(for exemple yesterday I had selling lot of Ford GT 2005 for 516 000CR / one but today I selling 2 for 50 000CR / one)
