The good news is that you already have a Ford Focus ST which is a well handling hot hatch that you would have loads of fun with on a track or autocross course.

Worst case, why not auto-x or track the Focus until the right car comes along.

You'll have fun, get your feet wet and in the process develop clearer sense for the type of track driving experience your looking for which will help solidify your car choice.

As folks have said in prior posts be patient. Not easy to do but you will be rewarded with a well sorted car.
