The hype is very real if you buy the correct ones. Your everyday variants won't hold much value, but the GT cars and special variants will absolutely hold their value, if not appreciate. I have four 911's ....three of them, have all increased in value ranging from 25% to 150% over the last several years. And they are not garage queens, I drive them, albeit they have lower miles.

Most of the Porsche owners I know are great people.
