My amt feels like a posh little go kart
You will be surprised. On long journeys with an auto, it's easy to go over limit as the car remains smooth at even 100mph. Erm, apparently. If I'm correct in what you're thinking, older small cars would rattle and shake and make a racket. my cdi auto holds it's own at high speeds. Flat out, it's a little hairy but still fairly solid.
