Hey Sav:
Picked mine up last night (G35C 6MT, Aero, etc.). I'm in heaven - just as fast as my Boxster S, with better low end torque - I came out of a 15-mph turn in fifth this morning (not paying attention), and it accelerated away smoothly without any laboring or objections starting at about 1200 RPM. My Porsche wouldn't have budged unless I dropped to third. I'm dying to exceed 4,000 RPM but I must be patient with that whole break-in thing.
Has anyone noticed a metallic clanging at highway speed that seems to come from between the rear speakers, or trunk. I put some stuff in the trunk that might be the cause (ice scraper, etc.), but I don't think so.
