. I'm sure you can imagin that I'm bursting with pride! Haha, I took it to this small time car show, all you have to do is pull up and park your car and you're in. I popped the hood and actually got a crowd! Haha, if I could do a back flip, I would. Thanks for the welcome into the club, I'll enjoy every minute of it!
