My Boxster S has been very reasonable on maintenance if you don't count the expense of the Super high performance Porsche N3 rated tires. I just turned 38,000 miles on mine and the only maintenance so far has been oil changes and an air filter. I just did an oil change last week and it cost me $5.97/qt. Mobil 1 0w40 X 10 quarts (takes 9.25 qtrs so you have to buy that 10th quart) and then the oil filter insert @ $21 and new oil plug crush-ring at 57 cents for grand total of $81.27 not including tax. My local Porsche dealer would charge $10/qtr and $150 labor (bastards!). Changing the oil on the Boxster is very easy and straight forward. You don't even have to access the engine compartment. I have a service manual and it looks like brake pad replacement is easy too. DIY and save money while getting to know your Boxster at the same time.
