My last check-up said I'm still ok.
Sure, the FC and the 944 are both inexpensive to get into, pretty reliable, parts aren't too expensive and there's lots of knowlege/support... relative to most other cars but not the E30.
I won't bother with buy-in cost because that depends on too many factors. If you score the right sucker you can get a very clean E30 with some easy to fix bugs for a grand or less. But there are also idiots asking close to 20 for mint ones thinking they're collectible...
As far as aftermarket, the E30 is supported by a dozen former and current racing outfits (incl ireland, akg, bimmerworld, turner), factory backed tuners (ac, dinan etc), and an entire subculture dedicated to making a plethora of [horrid] bodykits and various other rice garbage for them. FC? (without importing overnight from Japan)
With two huge forums dedicated to them (not BMW or 3 series, e30 - r3v and e30tech) there is a picture-story diy for anything you can ever need to know and there's a documented process for converting to standalone with basemaps galore (NA and various turbo levels), or swapping just about anything - from many other BMW engines, to an RB26 or LSx. For the latter, there's a $100 manual available which holds your hand step by step, with drawings of all custom parts and part numbers of obscure OEM stuff you will require. The M5x swap is so well documented that a kid who's got his Meccano down could do it.
As far as parts availability, a visit to any junkyard will conclude that argument in my favor (or a look around the streets, counting how many FCs and E30s you see).
And about reliability, again I didn't say the others are not reliable. I'm just saying that the E30 is on a different level of robustness. You have to hang around the community to appreciate how badly neglected and broken these cars can be and still not strand you.
I do concede about parts. Most maintenance bits like suspension are about on par.
