Were you commenting on the road speed or the body speed or age when you said 70-75 
More to the point for around town and little highway any car will do I would think. On version 2 or 3 you might choose a different car of course according to your budget. But in reality while budget comes into play we were not really talking about that factor much even if it has a bearing on it. I have seen a lot of high end cars in driveways where the owner is not really the owner.
If you nearing 85 mph, oh I meant age you might blow it all on one last chance to go where you have never gone. Don't they list cars here where the owner has departed for greener pastures... You know but then you will have to change your drive to a Triumph.
