OP here... I agree - a smooth downshift is satisfying. I'm glad the topic has created a vigorous discussion. It was a question that intrigued me...is it necessary or destructive or ???
As far as European preferences go: My wife and I recently visited Iceland. The bus that shuttled us from Keflavik to Reykjavik after we arrived was luxurious, modern, and the first manual transmission bus I have ridden in since grade school!
Automobile rentals are the same ... if someone wants a car with an automatic transmission they must reserve one.
BTW: Ring Road 1 is a wonderful driving experience! It would be a blast if the MX-5 could go with us next time ....
