Maverick,

There are options for aftermarket seats. Some use Sparcos and others use Carivaggio who recovers Porsche GT3 seats.
Also, I have a Callaway aftermarket shifter. It really helps the shift action.

This comparison is good. They are very evenly matched cars. You'll never see me bash anyones car. I'm a car nut, not a particular brand. My dream car is a GT3RS. Someday, I'll be able to afford one. Right now, my Boxster and Z06 are at different ends of the spectrum, but they are both great in their own unique way.
I think the bashing from some people is because they're scared. No, the interior isn't the greatest, but I only paid $70K for my car and the performance is incredible. If it's being compared to $100K+ cars, then that's great for my car! I can also go out and spend $10K on my interior if I so choose and have a custom interior.
