I think a very good place to take out your G35 SC is on Sunset Bl between the 405 and Sunset strip. Just make sure you do it very late at night(like after 3am) so that there is no traffic. Lots of curves and you can get a real good feel for how it handles without pushing the car during the break in period.

Sorry if I post too much, but I am very psyched at having this car. I've always driven compacts....my current car was an Escort...and its a thrill to have a car like this. I actually kept the escort so that I would not put too much milleage on the G35 SC but I have already put 1000 miles on it in two weeks
