Not to split hairs but the new Z4 M series has an inline 6. It is the current M3 engine minus 3 Hp because of the exhaust system design on the shorter wheelbase Z4 chassis. It is quite a piece though. Faster than a Boxster S in a straight line. I'd still take the Boxster S though. My old man just got an 06 Boxster S and it's a real honey. The new M3, however, is rumored to have a 400+hp V8. That will be a jewel if you ask me.

I had read somewhere a short while back that the Z4 M series coupe was to have the new V8 that is reportedly going into the M3 but I cannot seem to find it now. Perhaps it was a simple momentary lapse of reason...

I agree with you here too It's like everytime anyone mentions the words Vette or M3, the lines are drawn! People always fail to forget there is a price difference and more then just sheer numbers. Anyways, like you said, it is a Chevy, no matter how you look at it: the interiors are just plain ... well plain and cheap looking at times. I don't like passing judgement on any cars until I've driven one so let's just leave it at the appearance for now. If we all wanted raw speed and so-so interior at around what we paid for the G35, we would have bought the w-sti or evo, but we choose exactly what you said, a luxury coupe that is still fun to drive. Anyways, I'm already eyeing my next car as either a sports car (the Cayman or M3 perhaps) or a pure luxury car myself. Who knows, if there is a G45, maybe that car

That's my prediction as well. With the new 400hpCamaro and 425hp Dodge Hemi Challenger coupe coming out in 2008, I could see the need for a V8 coupe in Infiniti's lineup.

The M series Z4 roadster just came out and has the inline 6 from the current production 3 series based M3. The not yet released 2007 M3 coupe based on the 3 series is rumored to have a v-8. This engine may (hopefully) find it's way into a Z4M but the brand new Z4M is the I6 from the current 3 series based M3. The only V8 coupe offered by BMW at this time is the 6 series. No big deal. Again, I'm just splitting hairs.

Good luck with Cayman! Either one is worth a kidney to me (hell, I've got 2 of them). It must be nice to have that kind of scratch. I'm enlisted Air Force so they're out of my reach for now. Someday......
