No doubt it is somewhat more oriented to offroad, I am like you, I have several other cars, including some classics and so the IG will mainly be used for touring and camping trips etc but that will involve long highway drives as well. I have driven but only offroad, from a noise perspective I don’t think you need to worry, its very quiet for what it is and many of the reviewers have said the same, although I haven’t driven on the highway at speed so will have to see about that. In my offroad driving I didn’t notice the steering, obviously the reviews have called that out. Owning several classics, I am pretty sure I can get used to the steering, watch the most recent video from Ingmar the Hard Way Home winner and he shows that there is a little looseness in the centre when the steering is unloaded but seems pretty precise when you load it up to corner. Ultimately though it’s a personal thing and no one can say whether you can live with it all except you. The road manners, steering aside, by all accounts is extremely good and the seats very comfortable so I am pretty sure it will be a good highway cruiser as well as offroad weapon.
