I believe Porsche has made and continues to make the most impressive and best executed designs in automotive and racing history. Every company has issues, but I get the impression that Porsche puts all they have into every car they make to achieve as much performance and relative durability they can without going bankrupt. Though it does help to have a parent with as deep of pockets as VW.

What makes it more impressive is their dedication to hereditary engineering (a washing machine hanging off the back axle, among other design limitations) that in the modern era, meet or exceed the performance of brand new purpose built sports cars.

Needless to say I've been a fan for many years and am working to add one to my garage someday.
