I have to watch the 300D on the interstate, it's easy to get in the habit of "pushing" a bit in traffic and ending up at 100 mph all the time.

Milage is good -- 31 to 34 if I can keep it under 75, right at 30 if I can't.

I have to stop every couple hours these days, my knees swell if I sit too long -- and 600 miles at 70 mph is a LONG time -- as in Evansville to Macon, GA!
