Yaris long term durability champ vs FR-S and Miata

[regal]

I remember an early 90's Accent I had that needed rotors, turns out they were integral to the hub and replacement was more than the car was worth, a car totaled because it needed rotors, unbelieveable but true.

So I got a 90's civic which was the leader for a budget car that would last forever if you changed the timing belt/water pump. Not only that it handled and performed like a dream with good springs and shocks.

I replaced my civic with a new 2009 Yaris because of the reports of the Yaris engine lasting forever plus it has a timing chain. Its a very durable car in manual transmission form. Problem is no double wishbone suspension on all four corners, not even IRS (civics dropped that critical feature by then also). With TRD springs, shocks, 15" aluminum rims the Yaris handles decent, but just not as fun as the good old EG civic.

So I've been looking at the FR-S or maybe even a Miata. Do we think these cars will have the long term low maintenance cost/reliability/lack of major breakdown as the Yaris/Civic ? At one time I almost bought an MR2 Spyder but learned of the ceramic catalysts blowing into the cylinders debacle, what a disaster that turned into. Not wanting a repeat of that no matter how fun to drive, if the long block can't make 300k miles I don't want it.

So die-hard Toyota million mile enthusiasts, does the FR-S design look as bullet proof as the mighty 2nd gen Yaris ?
