What Scott said.
Come out and run as a novice morning and afternoon every autocross and save up for a track day and tires.
You will get your ass handed to you by some old dudes in Miatas and random shitboxes, but that is OK. It is not the car. We do not teach people to drive in this country, just the rules to not get a ticket. It is not your fault, but you can do something about it.
Come learn with a great group of people.
