I would like to buy a Mazdaspeed3. However, the IIHS has rated the Mazda3 seats as marginal. I would appreciate it if someone could assist me in positively answering the following two questions:

1. Since the Mazda3 is built on the Ford C1 platform, the same platform used for the Volvo C30 / C70 / S40 & V50, are any of these Volvo WHIPS-equipped seats interchangeable with the Mazdaspeed3 front seats? Is the seat mount bolt pattern the same?
2. Per Wikipedia, "the safety and electrical components are shared" among the Ford C1 platform models. If this is correct, shouldn't the Mazda3 control module be compatible with either the Mazda3 or Volvo seat, its weight sensor, and its built-in side air bag? Is the Volvo WHIPS-equipped seat fully compatible with all safety systems in the MS3?

Thanks!!
