I have the same impression. Even at max RPM one thinks, that the engine could easily rev higher. But there is more than the engine. Suspension, brakes, interior, gearbox are flawless too.

There is a lot of talk here about the Turbo being boring and I tend to agree somehow.  At low rpm it sounds and feels like an everyday car, but when you push it, it becomes an animal which is also very capable on a track.  I can not think of any other car with these properties. As others have said already: If you can afford just one car, then it's the Turbo. If you can afford more than one it's likely not.
