Pick any part on a 911 and you can either get a reproduction part or uprated component from not just one but several suppliers - you really are spoilt. Even Porsche will supply a lot of parts brand new for you. With Zs I feel like there's only one good supplier for some parts, and for some other parts none at all (any good rear valance or rear quarter panels available haha). Even for off the shelf suspension and brake packages, you only really have two to choose from - arizonazcar and T3.
I've since sold my old porsche because parts just got too expensive, but it was one of those cars you could get anything for.
I've actually been living in Tokyo and the US for the past few years, so I'm familiar with car scenes over there, plus visited the shops and museums, but I personally feel like the aftermarket support for Zs isn't where it should be. I used to own 2 early mx5s and tracked them, and parts for those were plentiful. You also had a ton of options when it came to modifying them. But then again ... miata.
I'm in full support for the Z lol but that's what I think is holding it back. If LHD numbers die off and we get some more aftermarket support, it'll take the Z to the next price level haha.
