Can we please have the iconic 95 honda accord race car. JACCS. The car is a legend in the race world and is still not in any game.
I’d like to see a 2008 Ford Escape 3.0L V6
I drive one and mine will never do anything impressive so I’d like to see what I can do in Forza with one.
I hope you get your Escape and with that, I would like to see my daily driver as well, it’s a 2015 Jeep Cherokee Trailhawk painted Mango Tango. I love it and it goes about my daily routine with little fanfare, so pushing it to its limits in Horizon 4 would be great fun.
How about it Playground games? Ford Escape and Jeep Cherokee Trailhawk.
I’d like to see all the cars from FH3 plus these additions:
Aston Martin DB4 GT Zagato

I’d also like to see more concept and race cars both past and present and from GT1 especially. There also needs to be a revival of past cars especially from FM4.
I’m wishing they add
1995 Ford GT90,
2003 Ford F-150 lightning,
1970 Ford Boss 429 Mustang, and
2012 Shelby GT500 Supersnake.
I so agree with you!
I think all forza horizon is missing is the diesels i would love to have some diesels in here
Here is the list of diesels i want in fh4
DODGE
1993 dodge cummins 12 valve 5.9
2002 dodge cummins 24 valve 5.9
2009 dodge cummins 6.7
2017 mega cab cummins 6.7
FORD
1992 7.3 idi
1996 7.3 powerstroke
2006 6.0 4 door powerstroke
2008 6.4 4 door powerstroke
2016 6.7 4 door powerstoke
I would also love to see some chevys and some TDI’s like the Volkswagen
1934 Austin 7
1935 Morris 8 Tourer
Both known to us old farts from the BBC series All Creatures Big and Small. It would be so cool to cruise the country in one of those oldtimers.
2015 Bentley EXP 10 Speed 6 Concept
2018 Abarth 124 Spider
1975 Volvo 242
To make me happy:
DODGE
First Gen - 1991-1995 VIPER R/T10 - What do we need to do to finally get the original in Forza??
Second Gen - 1996-2002 VIPER GTS Coupe - I know we always get the 1999 GTS ACR, but for once I’d also want the basic, everyone can buy it, model.
Third & Fourth Gen - Don’t care much about these, but surely 1 or 2 will make an appearance.
Fifth Gen - 2012-2017 VIPER GTS and GTS-R - If something in addition to these, be my guests 
Just been made aware of this one. I think it would fit very well.
1961 Ford Thunderbird Custom Roadster “Thunderflite”
I hope for one of the expansion packs, they do a Fast and Furious one, like Horizon 2. Add all the FF cars from the previous Forza DLC’s, and shove it all into one big pack. Including such cars as:
Forza Horizon Present’s Fast and Furious
Fast & Furious Car Pack
The Fate of the Furious Car Pack
If I had to choose which car gets added, I’d pick the Ice Charger. That car would make messing about on frozen lakes so fun! And maybe, pair it up with the Hoonicorn Mustang? That would be awesome!
