My 2003S did leak even though I did not notice. The repair was covered under the warranty. No charge. Would recommend buying the car from a dealer for warranty coverage. Preferably under the Porsche certified used cars. They may cost more but at least they are the safer and saner way to mitigate any big repairs. Remember that a Porsche is an expensive car and the maintenance as well as the repairs run into serious money. That being said the only issues I've had with my car has been the clutch and the seal. The clutch ended up costing me less because it was done in conjunction with the seal repair. I use my car every day for work and had it for almost 3 years and close to 40,000 miles. Judge from there. I hope this was helpful. Good luck in your hunt for the Porsche of your dreams.
