I am also new and haven't even bought yet. Sorry I can't help with your question. But, how would you rate the power on that 530? And what have you seen for highway mileage and at what speed is that?
Thanks,
James

Decent mileage

According to the onboard computer, I've gotten 34mpg on the freeway at around 75mph. 28mpg is not unusual on the fwy.

I get an average of about 22mpg city/hwy.

Power is fine, IF it's in teh sport mode.
