Uh oh...now your in trouble.... This is the beginning of the end of all your money. Look at your bank account....it will never have that much money in it again!
Track driving is an addiction that can be more expensive than any drug habit. You will have an absolute blast, and will want to go again. You will want to do start doing DE's, but will soon learn that your 914 is actually slow compared to the cars you drove at the school, so you will soon either start upgrading your car, or looking to get another track-only car. Then comes upgrading that car, new stickier tires, the trailer, tow vehicle, etc. etc. etc.....
Sorry...you're now toast. Ask me how I know...

Welcome to the insanity. And don't say you weren't warned....
Have fun!!
