Okay, all the cars I’d like to see all stick to a certain theme that I fear will be the reason none of them will make it into the game, but I might as well add my 2 cents. Let’s see if you can identify the pattern here. 
Something tells me none of these cars will ever make it into any Forza game, but I may as well ask for them anyway in case they want to.

We’re still missing the E60 BMW M5 in the current generation of Forza and it’s quite an interesting and different experience to the other M5s.
It is very fitting that Horizon 3 is in Australia as we’re about to see the demise of our local car industry. The Holdens and Fords currently being manufactured here are the last of their kind. Horizon 3 should make for a lovely send off for these iconic vehicles which are about to reach their end of life.
With that in mind I do hope that there is room to immortalise them in Horizon 3
The FPV GT F 351 is featured, which is a good send off for (already deceased) FPV but perhaps there could be room for either the 2016 XR6 Sprint or 2016 XR8 Sprint?
Yes they are quite similiar, but the GT F is technically an FPV, while the two XR models are technically mainstream Fords.
On the General Motors side, the LSA powered HSV GTS and even the LS3 powered Commodore SS would be welcome.
And it may not be the most appropriate place, but while we’re on the subject of Australia I hope to plant a seed for future Motorsports titles:
Gibson Motorsports Nissans - look them up
-EDIT- corrected M5 to E60 - fingers did not cooperate with brain when I first wrote it

In this time of bringing back some great features of previous Forza’s LET’S GET A DELOREAN BACK! And how cool would it be if the “widebody” kit for that was the back to the future conversion. I know that’s a lot to ask due to licensing. But at least a delorean!
