Ummm, this is a HIGHLY relative question depending on the body structure of the driver and whether or not you can use cruise control the majority of the time or not.
I rarely drive my IS out of town, so I've only driven from Raleigh to Charlotte once and once to Hampton, VA. Both drives kinda sucked for me, but I'm also 6'2", 265 lbs with fairly long legs. Both routes had crazy amounts of traffic and the IS seriously wore me out when I couldn't use cruise control.
I wouldn't say that. I do a lot of driving.
Just put 700 miles this weekend. 900 2 weeks ago. Going for 1500 this week. Gonna go back to regular 1300 miles/month after that.
The car suits me well.
There's more than enough room for 2 people. 4 gets to be a little crammed up. Seats feel comfy for my body structure (5'9").
Yep, the IS wears me out (he he) in traffic too, with all the zipping through it I end up doing.
