What kind of work are you having done on your Porsche that is costing that much every year?
They are for sure expensive to have work done, but having said that I've only needed to change oil so far in 3 years....will need a set of tires after this season but even that is under two grand. They tend to be very reliable vehicles. Weekend track meets will take a toll on brakes and rubber but that's to be expected...and I don't track mine anyway.
