Overall reliability/durability of the Boxster:

The problem with a site such as this is that people typically only post when they have had a problem. This leads to a slanted view of the cars as a whole, particularly since the original 986 Boxsters are now between 10 and 17 years old (the 2014 MY starts production in the next month). What sort of reilability would one expect from a 10, let alone 17 year old Toyota that was driven as hard as most Porsches? Herewith my list of positves in terms of reliability/durability of the Boxster, based upon my own experience, as well as the reports reviewed on this and other sites:

1. BODY/PAINT - Porsche's fully galvanized, laser welded bodies are as rust resistant as a steel body can be made. I have yet to see a rusted 986 Porsche, even when driven on salted roads in northern climates. Most Boxsters still have their original paint and, apart from dents and stone damage, have a finish that has held up remarkably well. Compare that to Toyotas, Mazdas, Nissans etc. of the same vintage.

2. TOP - Excellent quaility German cloth tops and a well-engineered convertible top mechanism that has proven remarkably reliable compared to many other convertible tops, in spite of its complexity. Due to the numbers produced, replacement tops are readily available at low cost.

3. INTERIOR - Sometimes criticized for cheap-looking materials, even the interiors in original Boxsters have held up remarkably well over the years - especially for an interior that is often exposed to direct sunlight. Have you ever seen a cracked dash in a Boxster?

4. BRAKES - Unlike many cars where calipers need replacement with almost every brake job, the Brembo 4 piston monoblock calipers have proven to be not only very effective, but remarkably durable.

5. STEERING - Not only does it provide accuracy and incredible feedback, but few owners have had to replace rack and pinion gears, steering racks and power-steering pumps. Compare that to the frequently replaced (at over $3000.00) electric power steering units on the BMW Z3 and Z4!

TRANSMISSION/CLUTCH - Unless abused (not unusual in cars that rev high and are often shifted quickly and sometimes inexpertly), the transmissions rarely fail. Compare that to the epidemic of failures in the Chrysler minivan, which is rarely driven hard! Clutches too can last up to 200,000 miles (see Pedro, of pderosboard), even when tracked. Go for high rev starts with the big rear tires, or fail to match revs on upshifts/downshifts, and yes, you can burn them out quickly. Drive them smoothly and they tend to last for a considerable period for a performance car.

SUSPENSION - Yes, ball joints cannot be replaced separately, but in cars that are not abused/driven on very rough roads, it is common to get 80 - 100,000 miles before components need replacement. Considering the stress that the suspension gets in hard cornering with relatively stiff springs and bushings (all required for precise handling), that isn't bad!

ELECTRICAL SYSTEM - A vast improvement over earlier German cars, Boxsters rarely have failures with their charging system, instrument clusters, power top/window motors and digital HVAC controls. The only common failures not due to abuse are the ignition switch (a $35.00 part from Audi and about 1.5 hours labour) and. less frequently, the light switch (an easy, if slightly more expensive fix). The immobilizers can fail if people allow water to accumulate in the car due to poor maintenance - holes in the back window, failure to clean out the drains, leaving the top down in the rain.

COOLING SYSTEM - Remarkably good for a mid-engine design, which required radiators and fans in the front for an engine with air ducting fans in the rear. Compare the reliability with mid-engined Italian cars (including the early Fiat X-19's, not to mention Ferraris and Lambos, etc) and you'll see what I mean. Yes, some people have issues with the waterpump (although some last for over 200,000 miles with proper cooling system maintenance). Yes, coolant reservoir tanks have been known to fail, but what does one expect of a plastic piece that held extremely hot fluid under pressure for that number of years? Fortunately, neither is a terribly expensive repair and, the radiators, fans and even the hoses have proven to be remarkably reliable.

ENGINE - Apart from the A/OS (another now aged plastic piece that is relatively inexpensive to repair) AND IMS BEARINGS, these engines have also proven to be highly reliable if properly maintained. Even the IMS failure rate (much less than 1% for early dual-row bearings and 8-10% for later single-row), are not that horrible when one considers that this is regardless of age, mileage and maintenance schedule. In any event, there are fixes available.

Overall, for an old performance car that is typically driven hard, pretty good durability and reliablity IMO!
