A silly comparison really. Two completely different cars. I actually like the Mazdaspeed 6. Near German sedan performance for less than 30k. With all wheel drive it gets a great launch off the line. Decent handling and it looks nice and drives nice too.
Regularly outrun any seasoned Boxster at the track while dragging around 3600lbs?? Maybe if Scott Pruett is driving it. I'll look for you at Buttonwillow and Streets. I'll try and keep up in my worn out, 10 yr old underpowered car. Best single solo lap wins. Loser buys the steaks and beer.
