Why rush out and buy hardware before you "need" it and before you can use it the way you plan? (Presuming you're buying it to run AmigaOS.)
I'd recommend buying your Teron once AmigaOS4 is actually released.
Prices always go DOWN over time, not up, and nobody knows if the currently sold Terons also will be discontinued, with new models and configurations available, before AOS4 is released. Same thing with the other hardware you mentioned.
Your car, OTOH, is apparently "MUCH needed"...
