Add me to the 1,000 mile club from this past weekend. Car performed flawlessly on interstate. Got a little bit of buffering behind 18 wheelers but IMO it was on par with most other cars I've owned. GPS read that my fastest speed I traveled was 90.5mph - hard to say that there were witnesses to confirm that though.
Add a cruise and armrest and the car is transformed into a comfortable cruiser. I agree about the seat heaters. It is one thing I wish I would of ordered.
