Hi Steve and welcome back. If you have the time and budget to do some class racing I say go for it. You don't have to spend a lot of money if you don't want to there are lots of cars put there they can be purchased at a reasonable cost, they might not be the fastest in the class but you will be in the game and will have just as much fun. I happen to see a car on Facebook a couple days ago that might interest you. I don't know much about the car but I know the seller and he's a good guy. Here's a link to the racingjunk add.

Good luck and have fun!
