I had the same problem when I put my newly reupholstered seat in. It was pretty awkward at first... our other vehicle is a Mazda Miata sports car! However, after driving her for a few months now, the close steering wheel and the overall diameter is still awkward but I've gotten quite used to it. One of the biggest challenges I discovered is having to change my own mindset... I'm so used to driving modern vehicles that I've come to expect the luxuries. I have to keep reminding myself that my truck is almost as old as I am and man do I ever have a few faults!
So yes, you're right, the wheel is close quarters
and you'll have to make a decision about whether you can deal with it or not. But my advice is to drive her a bit first.
From where i sit, overall the "coolness" factor of driving the old 'Bolt overshadows her idiosyncracies! But I think I'll try and loose some weight anyways!
