Probably best to plan by time rather than mileage taking into account the type of roads you wish to travel on. Like others before when we are touring we wouldn't want to do more than 250 - 300 miles in a day but when I have been on my own and driving for a purpose A to B I have sometimes covered 400+. We have both found the older non-reclining sports seats very comfortable and improved by the addition of the inflatable lumber supports. One thing that I have noticed that I don't experience in our trusty Volvo is the need to take more comfort breaks. I put that down to the harder suspension!
