Yes.. some of them will. In order (assuming all are ORIGINAL and unmolested. once you start pulling 3-4 cars together to build 1, then, we know the market has become absurd
)
1) 914-6. only a couple thousand produced. Rare and exclusive. Most "100pt concours" examples can command $25-30K in the US. Suprisingly, this value is still less than the dollar adjusted 1970 sales price (They were $6k new)
2) '73-'74 2.0L. The more options the better. They were the next best "performing" 914 model
3) All others(1.7 or 1.8). These will come down to condition only. Some prefer the early 1.7 with its fixed seats, footrest and lighter weight vs the slightly less powerful and heavier 1.8l cars.
Now, can these be $50k-100K cars? yeesh. not for another 20 years is my guess. The 914's in the US never had the allure the 356's did. They were "bastard" Porsches. Unloved by all those who never owned one. Unliked by 911 and 356 owners who were "beaten" by them. Recall that they are not "fast" cars (same as the 356) but handled incredibly well.
Similar to 356 in that first - Speedsters are most desired, then cabs/convertibles, then coupes. Early cars, then later cars with the "b"s lagging behind.
Also, there are a lot of modded 914s. I call them the "r-group" equivalent. Customized. Bigger (911) motors, brakes etc. They don't derive price by actual value but by a buyers desire for a particular car.
