I think it has to do with several things that vary from different areas of the country,supply,demand,economics and peoples priorities can change in a very short time frame due to family,health job changes,again economics plays a major role in decision making for toys and large purchases,for example I've talked with guys making 50k or more a yr which they consider low or average but where I am geographically it's enough to live quite well and have excess money to buy things you normally could'nt afford...and I've also seen people making 20k or less and have toys,sometimes they sit and do nothing with them due to the lack of funds or lose interest in them... some people are impulse buyers,some are hoarders,there are many things that drive the market for classics but I would be fairly safe in saying it's mainly economics that sets the pace and from my standpoint it aint looking very well ,if I didnt already have my car and many parts and stuff already I would in no way be able to replicate it again at this point in time due to my health and finances and age and my lack of desire to mix it up or drive to gotta have I once had..once not so long ago had 5-6 projects,now only one and I'm struggling to maintain that in terms of ambition/money to complete it,with all that stated,I am in the catagory of 5-6 yrs back of moving alot of parts and cars[10-15 cars a yr plus tons of parts and parts cars] to almost zero..supplies dried up ,cars dissapeared,scrappers took alot of good stuff away,money got tighter and values plumented,slowly they have made a rocky climb but no way as good as they were but they are going up over time but I doubt they will ever get back totally where they were then but I've been wrong before,these reality shows like 'flippin cars' '*** monkey garage' and such is all BS for the most part and 'regular' people dont play by those rules for the most part,unless you have tons of money you are pretty limited to what you can do especially if you got a family and obligations and just trying to survive on what you get to take home which in my case I usually dont make it home with anything left over....So,I feel that economics is the main reason and I have found that there is a real lack of demand for what I once did on a large scale as in there are far fewer peoples buying or are interested in it as a whole...
