I'm sure you'll find your own 'pace', which for me/us is dictated by the nature of the journey. For example, if you're in holiday mode setting then it's everything off & stowed, with a nice bimble going on, so around 100 miles with lots of tea & pee stops.
Heading for a destination against a setting sun or simply the need to get there, then it's hood up, ear plugs in & motorways..
You can do some serious miles if you choose, but the noise, wind blast and traffic around you all conspire some days.
In truth, it's a leisure car and one to enjoy, so a bit of Fangio on a nice part mixed with some hunkering down and humming to yourself is usually the order of the day.
I actually don't like driving to a timescale any longer, so I'd rather plan an overnighter to spread the miles these days.
Half the fun is trying things out, so enjoy it..!
