I've always believed that cars designed and built to be "collectible" are destined to be bad investments over the long haul... Its the stuff people DIDN'T cherish and save in large quantities that end up being worth a ton of money in later years... If everyone who bought a 69 ZL1 (only 69 made) would have left the window stickers in them and put them in dry climate controlled storage without driving them for 30 years, would they be worth as much as they are today? I doubt it... the fact they they were pounded on, cut up, raced, butchered, wrecked, and generally used and abused is what makes mint originals worth so much today... the fact that they WEREN'T collectible when they were built is what makes them "precious" today. As long as everyone buying something keeps it perfect and "collects" it, the value will never go up as a "collectible" and will actually depriciate as something newer and "more collectible" is introduced and these same folks want out of their previous "investment". An example that comes to mind is my 97 Camaro 30th Anniversary SS, one of "only" 100 or so built without T tops and with the 6 speed , but I could find 6 more exactly like it, with ultra low miles and all the paperwork etc. easier than I could find a mint condition "standard issue" run-of the-mill Z28 from the same year, in which they built 1000's of... The reason is, everyone who bought the 30th Anny cars, pace cars, limited edition this and that, etc... because they were 'collectible" and stashed them away for 10 years never enjoying or driving them, while everyone else went out and hammered on their "regular" z's, racking up miles and had fun with them. Now all those cars have 100K+ miles, been hit and painted and dented, and generally just worn out. Very few standard Z28s have survived in mint shape. In actuality, THOSE cars are rarer than the "limited edition" Anniversary editions are today. Moral of the story, if you are buying a new car marketed as "collectible" you're probably gonna lose your a$$ eventually.
