DD mine up 101 in the bay area every day. I like the adrenaline rush I get from merging onto the freeway every day as a good substitute for morning coffee. I do about 15 miles to work and, to be honest, if I had to do more I'd probably trade her in for a 60-series.
If you are on the freeway in a 40, unless the firewall and floor has been heavily insulated, it is going to be very loud. When I give a nearby coworker a ride home once or twice a week, we end up yelling at each other.
And yes, the gas sucks. The way I look at it, you are paying about $100 extra a month to not drive a plastic modern piece of sh*t.
Fun as s*** though, especially when you take shortcuts over curbs.
Cheers,
