2003 Porsche Boxster S Reviews

Piece of shit!!
Bought my boxster s used with only 18K and have driven 9k in the past year. So far i've replaced the oil separator, ignition switch, clutch cable, and glued the top at the back along the truck. Last month the temp light came on while idling at the gas pump. I shut the engine off added water to the reservoir and had it towed to the mechanic. He started it up and couldn't find anything wrong. He drove it for a cpl of days and gave it back.
A week later the oil pressure light came on....towed it to the mechanic. He has the engine in a hundred pieces and says that there is an internal oil leak and the bearings are scored........$5K to get this disaster of a car out of the shop...
DO NOT BUY A PORSCHE!!!..........

I purchased my 986S new in Dec 2002. I have owned 14 new-purchase German vehicles (Audi, VW, & BMW) since 1976 - this Boxster S is heads & shoulders above the rest in terms of performance (to be expected) and reliability. Other than an initial adjustment of the convert. top, installing speed bleeder valves, and a new battery at 5 yrs nothing other than annual maintenance has been required. Even all the bulbs & key battery are original and functional. My experience is pretty typical if the JD Power #1 rating for Porsche is accurate, and it likely is based on the experiences of my Porsche Club friends.

I absolutely love driving this car, but compared to the other reviews left here, I must have gotten a lemon. I purchased my 2003 Boxster S convertible used two years ago with only 37K miles on it, and it seems like I have to sink $2,000 into it every few months. I only had it out of the shop for 10 days and It now needs a new clutch at $2500. I think I've put $7500 into this car in 2 years. So, buyer beware. I hope all other buyers have better luck than I have had.

I purchased this car at 77k miles over a month ago and I am very happy with it. I can't say too much to the mechanical reliablity since I haven't owned it long but the previous owner has had to have a few transmissions seals replaced and the engine was replaced under warranty it 30k. He has taken good care of it so I don't anticpate any issues. I have already taken the car on a road course type track and it did EXCELLENT! 4 20 minute intervals of hard driving and it had no problems. The car handles beautifully and has good power. I highly recommend one.

The finest car I've owned and driven. Makes my old SLK seem like a sedan. The Boxster S is pure joy form acceleration, handling, and braking. Seven years young and just hit 20k miles, but she is still showroom clean and never a single problem. Looks like I might have to put my first set of new tires on her before the winter. Not bad. : )
