As I read through this, I wondered how long before the x type came up. I don't see a reason not to do it. I couldn't afford it as of today, but I also can't afford the bmw 3 series I want. Think about the guy that said ...I'm gonna put a CHEVY (GM, totally not suitable for a Mazda) engine and tranny in my RX-7. Tell me he didn't get chastised.
I get so tired of everyone on here getting attacked because they have an idea that is a little different and out there. We have electricity in nearly every home in america now. Thomas Eddison saw that one coming, and you can blame a few crazy engineers for the box you're sitting in front of now as stated by an IBM spokesperson ...Computers will never be used in the home, they're far too expensive and large.
I say save your pennies and go for it. Your car is for you, not for these flamers and doubters.
