Have your dealer go over/inspect the car with you front front to back. If you will be doing some/all of your own maintenance, have them show you the items that should be checked/adjusted on a regular basis.
Set up another day to come back with the car (1 or 2 weeks after delivery, or as soon as you get at least 500 miles on it) and have them recheck the car (driveshaft bolt torque, header bolts, suspension, ect).
Have them show you how to install the top and side curtains, even if you will 'never' use them!!!
Check out the 'Second Strike' website for Superformance owners and register (if you already haven't done so)
http://www.secondstrike.com
You may also wish to join SCOF (again, if you already haven't done so)
http://performanceunlimited.com/scof/subscribe.html
Both the above are excellent sources of info for Superformance owners, in addition to Club Cobra.
Be prepared for some excitement when you mash the 'go' pedal!!! Make sure you are pointed the direction you want to go :-)
Enjoy, and be careful,
