When the rubber meets the road our cars are nothing more then a hobby. If you fly radio controlled models that you either buy or build it’s the reward of showing and flying your airship with a transmitter, if you crash you pick up the pieces and go again either buy or build.  When you buy a boat, you go into it to use the boat, to sail, or fish, or wake board, or just cruise;, maintenance, dock fees are high, but you love it, so you do it.  Some say boating is pouring money into a waterhole, but you do it anyway. When you go racing, you go to win, you pick your class and go for it, tires oil, fuel, transporting a race car, your in it full andyou love it.ITS NOT ABOUT THE MONEY OR SOMEONES PERCEIVED  VALUE, ITS ABOUT THE SPIRT OF WHAT YOU BUILD, HOW YOU BUILD AND HOW MUCH ENJOYMENT YOU GET FROM YOUR BUILD.
All this other verbiage on affecting value is moot, at least in my mind.  Do something cool and to the best of your ability then enjoy the rewards of what you have accomplished. Meet like minded people to share information and appreciation
