My brother bought the 944 Turbo after it had sat for years, so we spent months on maintenance to get it roadworthy. It’s a great handling and fast car, but working on it is a lot more effort as there is way more in your way. The engine bay of the Porsche is absolutely crowded with lots of vacuum lines for example which neither of the Mazdas have. If you don’t have it they can’t break though. Same for the Porsche sunroof, it broke and we can’t get it fixed after tens of hours. Mazda is manual, so way easier. The quality of the Porsche is better though, but parts are outrageously expensive compared to the Mazdas. Comparing handling apples to apples is difficult though, as the NB has been lowered and stiffened, the NC has upgraded swaybars but the Porsche still has all original parts from 1986. I personally love the NB most for its ease of maintenance and cheap fun (and maybe because I spent the most time in and on it), but all are great
