Most people who buy Porsche’s do not typically have to worry about the price of parts and so Porsche know they can charge a premium for those parts. They're no conjurers of cheap tricks. If the cost of Cayman 718 parts is a genuine concern, you have purchased the wrong car and you really shouldn’t own a Porsche. Porsche parts are expensive because customers are willing to pay that much. It’s a premium brand, and owners are willing to pay premium prices to have their cars serviced. Turns out, Porsche has a long history of quality production. Sometimes Porsche parts are going to be tough to find and with import duties on top of everything, insanely expensive. Personally, I think if Porsche stresses you out financially you should probably get rid of it before you are staring down an insane bill of labor and a seriously expensive part. The way in which Porsche manufacture their cars in my opinion is second to none. The product testing, research and development that go into each model ensures that they can withstand the rigors driving experience. A genuine Porsche part will last much longer than a part built to the same design and not tested in the same manner as Porsche. Porsche part may be 10/15% costlier than another from an alternative non-genuine European parts manufacturer. However, the Porsche part may have 50% more serviceable life in it, giving greater value for money and a 2-year warranty for genuine Porsche parts, unlikely event a genuine Porsche part did fail, Porsche will provide a replacement. I’m extremely happy I owned a Porsche 718 Cayman and I can afford the maintenance that is required.
