The DSMs are very reliable, it all depends on the way you treat it. As I've said, I've had three of them, and never had a problem with any of them, maintained it, changed oil and it never quit.
Mach10 says that they are fast, yet unreliable. That's not true at all. But if you really want to think about it that way, and you really do believe that they are unreliable, that puts the fiero way down in reliability. Just in comparison b/w the Turbo DSMs and the GT Fiero, they do have very comparable performance, the DSM is probably faster than the Fiero, the fiero, imo, handles better. My DSM gets 28 MPG city driving, fiero is about 18. The fiero is a nightmare when it comes down to how well it holds up, before something else breaks. That rarely happens on a DSM, aside from Triad's obsession with transmission destruction (which I find questionable).
How can you compare a Japanese engine/vehicle to an American one? You can't. American automobiles suck, of course you see the foriegn cars getting it right the first time around. That's just the nature of the beast.
With that all said, I would never, ever trade my Fiero for anything in the world, even if it is a maintainance hell, and I very much look forward to getting another one, which puts the grand total up to 7 Fiero's!
