Is there a site that charts or graphs Porsche values?

[Nextgen]

Hi all,

I can remember 18 years ago, graduating college and somehow trying to justify a 911. At that time, (if my memory serves me) the 1973-76 cars were at the bottom of the depreciation curve (You'd often see <$10K well abused models in Autotrader).

The more desirable (or so I thought) mid-80's models were considerably more expensive. As were the older ones made in the 60s.

Of course, things have changed and a quick perusal of autotrader tells me the 70s cars are selling at a premium to the mid-80s cars

Is there a site that compiles or tracks the values of the various 911 models in an easily accessible format? I can go through Ebay and Autotrader and get an idea, but its hardly a scientific study. As much interest as there is in Porsches, I thought it's possible someone has already done the work for me. (It appears the Blue Book and Edmunds don't go back far enough.)

I have no delusions about buying an classic 911 and watching my 'investment' grow, but potential depreciation/appreciation values would be a factor as I restart my search for a 911 (after a 18 year delay .)

Many thanks.

Excellence magazine has some of the info you are looking for, although there is always heated debate here regarding the accuracy of their values. I think they are a good starting point, and should help you figure out values generally on a relative basis. Info used to be available online, but I think you now must purchase the guide.
