I've driven a lot of those expensive cars as driver for a rental company that rent out those (to an exclusive public only) in Europe, and i agree, the 911 is the best car i've driven. Especially the latest series (from the 993 to now), they are technically way better than any Ferrari or Lambo or Bugatti. And yes, i've also been behind the steer of those on occasions. Ferrari, when they work, are great altough, especially in giving you the impression of being the fastest. Lambo's and Bugatti's are just loud and shouty (and go very fast), but are not that good for the rest.
But that is indeed not the point of those super expensive cars, their point is exclusivity, not top performance. That's why wealthy people pay ridiculous prices to buy or rent them. And that is why the company i work for as (freelance) driver does not even have a website. It's just a phonenumber that you have if you're high class enough to get access to those. And if you don't have that number, you're not high class enough to rent them ...
