The Golf R is a multi-purpose, multi-practical, performance car for all weather conditions. Multidimensional > Single purpose. Less than 1% will ever take their car or sportbike on track, so it's all about how the vehicle performs in all weather, all season conditions. This is why the Golf R is exceptional. It's a jack of all trades. Great commuter when you want it to be, with pretty good fuel economy. Then it's an exceptional awd performance car when you want to beat on the throttle, and go turning. It can seat kids or adults in the back, turns into a small suv in terms of storage capacity with the rear seats folded. Even has rear vents for occupants. So given the multi-use, practicality, performance on tap, luxury interior, premium sound system, and large overhead for tuning and bolts ons....worth every penny of what they charge for it.
Few cars can do so much so well.
