Gee, why not ask what is the best oil, or should you run antifreeze, or what kind of tire.... everyone has an opinion!
So here is mine. I have a 1930 Tudor; this car is a driver, is not perfect but was 'restored' (debatable as to the quality of the work) many years ago. Other than a second tail light on the fender, it has no other added options, not even an outside mirror, although I am working on adding seat belts.
This car has been the most perfect car for me and my wife. The Tudor is huge inside particularly for back seat passengers, and the windows open fully in the back for great ventilation in the summer.
But all in all, I think the best car is the one which touches your heart. If you find a nice car that has been lovingly maintained and is a reasonable price, go for it. The only bad things would be the coupes are difficult for tall folks and the roadsters are more of a parade car as far as comfort is concerned.
Otherwise, it's up to you! One thing is for sure, they are all a ton of fun.
