With gas the price it is, most of my drive is a 25 mile to work and 25 miles back, 90 0/0 all highway. I put cruise at 55mph and drive like a granny. I stay in the far right lane, and don't run into too many problems. What very little intown I do, most is without a/c on. My figures don't reflect most conti's but I am thrilled with what I am getting. This is even using regular gas as opposed to 91 0/0 premium. Just changed cabin filter, air filter, pvc valve, and fuel filter valve, keep front tires at 30 lbs psi and rears at 28 psi.
Everything is factory and I am a 57 year old man driving like my 86 year old mom. Bubble is liable to break at any time, as I have only owned the car for five months so far. But am really loving it.
