Let's generally discuss FCs

In general, the FC has the most stupid wire harness configuration known to man. Convertible, convertible with air bag, audio system type 1,2,3,4,5, turbo or non tubro, Coupe with airbag or without airbag,Canadian, Federal or California.
The FC is the oldest car I have ever seen with what would be called a BCM today (mazda calls it the CPU). The FC, with its complicated electrical system, has MILES of freaking vacuum hoses and 5 vacuum control solenoids. It's almost like Mazda engineers said to themselves "we could make these electronic but **** it, lets control the complicated vacuum system with the complicated electronics system. I mean it works and it works well, I'll give them that, but when it stops working holy crap.
Most would deride the FC's emissions system but it works and it works really well. It is overly complicated and doesn't need to be for the same emission compliance but it works. My FC has always passed emissions easily. I had a completely stock GMC S-15 when I was a teenager with throttle body injection (fancy carburetor) air injection, EGR and a three way catalyst and it wouldn't pass for ****. It always either failed NOx or HC's. Turn the timing up to pass HC, it would fail NOx. Turn the timing down to pass NOx and it would fail HC. This was after replacing every emissions related component on the engine. I am not going to get into how I acquired inspection stickers for years after that. Living in an EPA non-attainment area is fun.
In general, The FC is a great car, just over engineered in some respects. I does have some pretty cool stuff from the factory considering it's an 1980's car.

I was thinking a Tii chassis with a GTUs engine. Almost the same thing, generally speaking.

In general, The brown foam tape on the wire harness sucks. It generally makes for a generally sticky mess.
Also, in general of course, the interior wire harness is not very well laid out.
In general, the FC has a better drag coefficient than a GT-R, and various other high performance vehicles.
RX7 FC = 0.31
GT-R = 0.34
Koenigsegg CCX = 0.32
Full list here, in general of course...

The engineers at mazda that decided a 50lb steel hood was a good idea at the time must have been smoking crack. Also, not continuing the J5 paint code to s5's was stupid. Generally speaking.

Generally speaking... Most of the crap these cars go through is just a consequence of age. The rest is from owners messing up to fix the cars after their age shows through.
^ About that Cd, the sport aero package drops that figure to 0.29. Forgot exactly what's included, but I know it included the front undertray, a spoiler, and something-something in front of the rear wheels. And let's not forget that the frontal surface area of the FC is pretty minuscule compared to the cars you just listed.
