GTR 2 with the Power & Glory 3 mod isn't a terrible place to start with. Some cars are actually quite easy to drive even without any assists on and you can have the game tell you when to brake for corners and what gear to do it in.
Things like rFactor (2), Game Stock Car, iRacing and NetKar Pro are a little more difficult to get in to imo than some SimBin titles (and PnG3) which I find slightly more forgiving in most cases.
Just don't forget to change the steering angle to 18-23 degrees (if you're using 900 degrees of rotation for the wheel) in some of the "older" sims to make the car steer faster (don't need to work the wheel like a mad man for hairpins). Some newer games/sims like rFactor 2 and pCARS (which is sadly not available for newcomers right now) can detect your wheel range on their own and have an option to automatically match the steering angle for the wheel rotation. You have to change the steering angle every time you start a session (practice, qualy, race) unless you save the setup, you should be able to find the steering angle under general (or something like that) settings/setup for the car.
