How to Save on Your Midlife Crisis

"Usually it's a car that they want to restore or one that has already been restored, or one that goes really fast," Foss says. "If it's a Porsche I tell them to go used. Do a little homework and you see that there are cars that are 1 to 3 years old; you can get a great car probably with very little mileage for a much better price."

Of course, there's more to a Porsche than the sticker price. Insurance will cost an average of more than $2,000 a year, depending on where you live, and gas could easily top $3,000 a year depending on how much it's driven. Add to that maintenance and repair costs and you've got an indulgence that can cost upwards of $15,000 extra after five years, as with this example of a used 2009 Porsche 911.

Plenty of midlifers save on some of those costs and still regain their sense of adventure with a cheaper and more fuel-efficient Harley(HOG) or a Tesla(TSLA) Roadster, but Foss says the Porsche is still in pole position.

"I don't get as much interest in Harleys as I used to," Foss says. "I don't know if it's just out of fashion or what, but I still get the Porsches. There's just no interest in electric cars or hybrids for these kinds of clients."
