Hey Ethan,
What about one of the Shelby GT's that is coming out the next few months? Park it out where people on southbound I-17 can see it when you are at work, might bring in more business for you and Bill. They will be avaliable with a manual transmission, and are rated at 325 Hp, but we know that will be increased when it is in your hands.
Keep the car you have!!!!!!!!!! Theres a thought. Bada++ ride , time and effort ?
