I am biased because I own an FC, but I love them (so much that this is my second one) I can honestly say out of all the cars I've owned (my current FC being my 5/6th) that the 2 rotary powered ones have by far been the most reliable. They handle superb, sound awesome, look awesome and I'm just talking about the FC here. The fd to the masses looks even better and the engine is just as reliable when looked after as reccomended. Regular oil and filter changes, correct warm up and cool down procedures and of course using the correct oil helps. It's also incredibly cool that Mazda reccomended you take the rotary engine up to its 'redline' at least once in every journey.
Rotary engines for the win with me, but they are not as easy to drift as s bodies due to the 50/50 weight ratio and the lighter 1308cc engine. The s body is more front heavy and this makes it easier to get sideways I beleive. Although I've never really tried to drift mine because I love it to much and don't wan't crash, scratch or dent it. It's also beyond my budget to drift right now, but back in topic. I just think that the RX-7 is a better build at in truth and the rotary engine is very misunderstood, tuning isn't as 'simple' as an sr20 but then it's not as complicated when going for higher figures, if you look into it you'll know what I mean.
