I'm half serious when I say I'm thinking of dumping my 401k into low mileage, manual transmission vehicles and storing them in the desert somewhere. Some of these they stopped making already and the prices have rocketed up (a fj cruiser that sold for 40k new in 2014 just sold for 108k last month) others this might be the last year that you'll be able to buy some of these, they aren't gonna be selling v8 manual mustangs forever, the last m3 manual is guaranteed to be a classic in the future, the Cadillac blackwing is a beast of a car for the value now but I don't think they'll be as sought after, you already can't get a manual Vette, I think manual miatas are a good bet though and civic si's

With manual transmissions disappearing in America, and the future looking a lot more electric, and hybrid motors in twenty to thirty years all the millennials retiring with money are gonna be looking for mint versions of these cars that remember wanting in high school but not being able to afford as weekend toys.
