Sounds good but I got this response from a email which will indicate that it’s never going to happen real shame like
Hello
Unfortunately the FM2 servers have been sunset and it’s not possible to obtain that achievement anymore. There is not a way for us to unlock the achievement for everyone.
I understand that has been their position but my point is that we have not offered to pay for what we are asking for. This is a computer program and anything can be done for a price. I have no idea what it would cost to reopen servers or program new ones but if they would quote us a price, we could see if there were enough people willing to pay to make it happen.
Another option could be that forzamotorsport.net could just add 10 points to everyones total score and we would not have to bother Turn 10 with restarting old servers.
I thought of another thing that could work. Turn 10 has said that the server that would allow the auction house has “sunsetted.” I was just recently able to complete the 1,000,000 points earned online challenge and got my Forza rewards points for it. What if they made another challenge like an online race or something that still does work and make it worth 10 points. That way we folks that are OCD about closing all of our red rings and having a perfect score could still do it even without the auction house.
Make F2, 3 and 4 back-compat on Xbox One and release them as a Classic Forza bundle! Money!
Fire up the servers again and bingo…
…Except I bet there would be licensing issues with cars and music etc. BOOOO.
Everyother auction house is still up in all the other older games cant see why they can open up the Forza Motorsport 2 up again makes no sence
.
We need this to get resolved by ANY “easy” solution (make the achievement pop with some other event in the game, or, worse case…provide the 10 REWARDS points to all that own the game) T10 can offer up! HELP!!!

I’d certainly back any possible ideas/suggestions made throughout this thread anyway, with regards to either bringing the Auction House itself back online, or simply some way of just giving us the achievement for it, so that this can count not only towards having 100% achievements, but also 100% FM2 Forza Rewards points/score for it too!
For once Turn 10, listen to your community of fans who still play a lot of the older titles in the series, especially those who invest time in going back through the games to increase their Forza Rewards points/tier etc for better rewards in each new-coming game, it only makes sense to make it possible for things to be obtainable, because having things unobtainable for whatever reason, especially Multiplayer/Online-ONLY, is just the worst thing you can do with achievements, especially knowing that one day you’d be pulling the plug on things and making a lot of it impossible to fully complete! 
Hi,
I queried the 1 million credit achievement a few years ago and thought both that and this one were not achievable. I am surprised to read it is possible to achieve 1 million credits still, though with the lack of online players on FM2, I certainly think it will be a struggle. I would very much hope that T10 could resolve this stressful problem for perfectionists like myself, with minimal inconvenience to them ie. just giving the achievement to anyone who has at least 1 achievement on FM2 for example. It genuinely stresses me out as someone with mild autism that i cannot fill in the last 25 points on the forza rewards circle for this game.
T10 please listen - I WAS a dedicated player of the Forza franchise. I have purchased everything up to FM6. The issue with these achievements has genuinely made me lose interest in the franchise because I know I’m unable to complete the FM2 achievements. This is sad for me - my friends want me to play FH4 but until I can complete my achievements and therefore rewards for FM2, I cannot complete FM6, then begin and complete FH3, FM7, and finally start FH4!
T10 - please solve the issue using minimal time/financial resources to yourselves.
Sincerely,
Dan
There have been petitions regarding this but they went nowhere apparently.
I also submitted a ticket to support but they basically just said “it won’t happen”.
So here we are after collecting 914 achievements, never being able to 100% our work - sad.
