Yeh I second that, usually the forum is for experiences others have to learn from. Ive heard a bunch of things go crazy on a lot of different new cars. My friends moms cadillac truck has been in and out of the shop over 10 times in the past year, its a 2006, my other buddies throwout bearing was shot at 5000mi on his 2006 Wrx, not to mention a lot of different Ecu problems. Stuff happens, this is the first production year for the MS3 so like all first you expect a few quirks here and there, to be fair I would listen in on the other cars forums your looking at and compare your final thoughts.
I honestly believe Mazda is a pretty solid company, I was a strong Dsm fan that in time was swayed, otherwise id have an Evo, I dont think any car is 100% perfect anymore, theres just too much stuff to go wrong, and turbo cars are extra sensitive.
