True, .2 is way more desirable as it fixed a lot of things.
I always find it weird that Youtubers who speculate about car values don't even talk about production numbers which is one main reason why some models become collectible and some won't.
Take Mercedes R129 for example. Amazing Bruno Sacco design, many people think it's the best SL ever made and Sacco himself said it's his "most perfect creation". Well those cars are all over the place... they made 213.000 R129's. The car was a massive success story and that's a huge number for a car that expensive (when new). And it's a solid car that lasts long time. Many of them still in great condition are on sale everywhere. But it will never become collectible. Maybe 600SL, 73 AMG but a base 300/500 SL... nope. Same with Corvettes... all boxes tick... it's a great car and timeless design. Guess what there's 358.000 C4 Vettes alone. Sure ZR1's and special models are a different story.
Those are GREAT cars to buy for the enthusiasts. Just like 996 and 997. I've dreamed of a 993 Turbo since I was a kid 993 Turbo with reasonable mileage is now 200K. I can never afford one of course... and it's a great dream car... but in reality I wouldn't even want to drive a car that costs that much. Where's the fun is that? Those RUF's, 964 Leichtbaus and 993 GT2's will never get driven anymore. Some white haired 80-year old milloinaires just buy those cars to their collections.
Then there are relatively low production number cars like Porsche 928 and BMW 850 (E31) with a lot of potential classic value. There's a lot of love for those cars but enthusiasts know how tough they are to maintain. That's why the prices never really went crazy (besides 850 CSI and 928 GTS).. Many Jaguars too. XKR-S and F-Type are among the best looking cars out there but people shy away from them because of their reputation as being money pits.
Porsches (genearally) are very reliable and the air cooled cars are superbly made. You only have to close the bank vauilt door and you'll see. Sure every model have their flaws like the new ones have bore scoring etc but those are relatively easy stuff compared to Italian sports cars. There are some old Porsches with insane mileages.
