That is the best way to look at buying a new-old car, prices for metal parts, interior parts are pricey and it doesn't take long to get ahead of ourselves with that love of the car blinding us a little when looking.. I try to look at it if a deal falls thru is there is one better around the corner and if not, im not broke trying to build one.. i think you have a good mind set with it, finish and enjoy the 70, see what comes up in the future. Thats one i would like to find, the 69-70 Satellite or RR.. More sentimental reasons then anything and im still not giving up on the idea, i never know what i may find later and have my 73 to enjoy until then.. Good decision i think you made.
