I speak mid-atlantic bland. Was once asked in London if I was a BBC announcer. The hardest for me is Bostonian more from speed. And of course I have not seen many people's lips for years. (Use hearing aids).)
For me all of my cars are about the same for comfort as long as I can recline far enough to take the weight of my back on my shoulders. Straight up am good for maybe a mile.
Crossfire coupe needed a sawzall and cutting disk to get back far enough.
