What used cars that are reasonably priced now, will be far more expensive in the future?

They have been making Miatas for over 35 years at this point. For a while 25 years ago, this seemed like such a great idea that EVERYONE built their own version of this idea. BMW was first with the Z3, Audi did the TT, Mercedes did the SLK, GM did the solstice and the sky, Porsche did the boxster. Toyota started earlier with the MR2, which was a different thing like Honda’s CRX (“our economy car, in 2-seat FUN-SIZED form’) but the MR-S version was a proper sports car and a convertible. Nissan made a convertible version of the Z. Honda did the S2000. This year, you can still get BMW’s z4 or Porsche’s boxster, but next year you can’t; this is the end for both of them. (Porsche will do an electric roadster soon. Won’t be cheap.) And so , next year just like back in 1995, your “inexpensive convertible sports car” choices will again be “Miata, or other color Miata.” And if one of us doesn’t spend the money on a new one pretty soon, they won’t be selling enough to make it worthwhile to keep building them, and then we’ll be down to ZERO inexpensive convertible sports cars. Is that what you want? Zero inexpensive sports cars? Do you remember the LAST time there were zero inexpensive sports cars? It SUCKED. MG and triumph and Fiat were wonderful to drive but were basically dogshit for reliability and quality, and they got expensive; by the early 80s, so they left, leaving only Alfa. Things were so bad, Ford made the EXP, an uglier Escort with only two seats and with hooded headlights that made it look like it was on quaaludea, which matched how it felt to drive. GM built us a plastic mid engine space ship with the 92 hp cast iron pushrod “iron duke” boat anchor behind the seats, backed up by a transmission so awful to shift that only ford could match it in the Taurus SHO. (Someone is still trying to find reverse in one of those somewhere to this day.) The fiero and the exp. Garbage. AND WE WERE GLAD TO HAVE THEM. IS THAT WHAT YOU WANT? DO YOU WANT A FIERO AND AN EXP BACK AGAIN?? Because if you don’t buy Miatas, they will TAKE THEM AWAY, and you’ll be sorry.
