Cool! its so nice thinking about it being delivered or in your case picking it up the next day. Building your hopes up and then sitting in the lovely new interior, smelling that new car smell, smiling whilst driving it in the sun. (sorry i sound like Roald Dahl, (Rolf Harris more like)) Then when you get home for some food, youll be reading the manual, how to adjust the stereo, or in the mk.2 172s case- climate control, auto lights..... alsorts!
Enjoy running it in, if you choose to do so. However, the ones that were enthusiastically run in, seemed to yield better bhp outputs when tested. I dont really know how mine was run in, as i bought it with 1000 miles on the clock (probably thrashed), and ive thrashed it ever since and its a flier!
