If we all had a Crystal Ball then we'd all be millionaires wouldn't we ?
I just cringe when I remember all the HK,T,G parts I threw out as they were just common things that wouldn't wear out in a 100 years, now those bits fetch around $150 each, unbelievable ! and don't start me on HQ, with the 467,000 Taxi cabs built and now for a flogged out 202 Trimatic Kingswood full of rust you can easily pay $6000.
25 years ago you couldn't find a hole big enough to bury them all in.
