I think you misunderstand petrol heads, most love a basic, no frills hot hatch even if they do own a super car. I'm quite a fan of the Suzuki Swift Sport, wicked fun little car and dirt cheap. The Fiesta ST is fantastic fun as well.
My car is one of those stupid fast cars and while you'll use a fraction of its speed on the road, what is fun is using the monster midrange grunt to fire it between bends on a twisty B road. There's also track days Nurburgring trips and V max top speed events. There's also the fact that a car with 500+ horsepower makes for an extremely relaxed motorway cruiser.
There are some car snobs but I'd say they're less common than instrument snobs. I've experienced more reverse car snobbery with people ranting at me about fuel consumption and too much power etc, etc and telling me I should get a sensible car, I have one and it does 90% of my miles.
