With respect, I am not even 40 - it's a given that in my lifetime we'll see $50K Z cars. We already have $30K Z cars... You are certainly entitled to your opinion - I am a collector of a ton of different things from baseball cards to old toys to cars - you can never say why someone appraises something at the level they do, but they do. Your original comment was "The collector car market-at-large just doesn't recognize the Japanese cars and their position in automotive history and thus doesn't place the value on them like muscle cars or vintage European and American cars." I've already stated Keith Martin and Sports Car Market have declared the Z car "collectible". Now, I will name a second authority - this month's "Motor Trend Classic" - one of the editors noted the 240Z as "highly collectible". The 240Z is collectible and recognized as such. Perhaps the second part of your statement with regards to value has some merit, but a good 240Z will outsell a good MGB, Triumph GT6, Triumph Spitfire, Opel GT, Corvair Monza, Alfa Romeo Spyder (maybe a wash), Porsche 914, 944, and older 911s. Based on that logic, I guess my Jaguar E-Type isn't collectible either since "mid year" Corvettes (1963 - 1967), Ferraris, Mopars, etc. will EASILY outsell it. I agree a 240Z won't be valued like a classic Ferrari - EVER. Just too many built and it's original mission as a mass production car dictates as much. However, I think you'll see steady increases in value for good examples - especially as many are modified or rusted. I would think Carl Beck might weigh in on this, he's pretty much the guru on this.
