Local Multiplayer Car Racing Game (PC)

[NoodleMaster]

I am an old school gamer who just got back in the loop with my son being old enough to take an interest in playing computer games.
I have been looking for a car racing game for PC with a local multiplayer option that was standard in any racing game in my days but to my surprise I don't seem to find any :(
NFS, Forza, Dirt, Project Cars or even Forza doesn't offer local multiplayer on PC and Grid 2 is no longer available.
Can someone please give me a valid tried and tested recommendation for a decent title with street/tuned cars (no F1) which allows me to race cars with my son on the same PC?
