Icebeast,
Mazda warranty is 3 year/50,000 miles bumper to bumper.
For that time, you get 24 hour roadside assistance.
You also get a loaner vehicle free of charge if the car is ever in service while still under warranty.
That said, while the FD3S was not a reliability king, I think if you check into consumer reports reliability ratings, you will find that all Mazda's in general have very high reliability ratings, and I would expect nothing different from the RX-8
