The Porsche is an affordable, sexy and stylish sports car that has what it takes to turn heads without making the outlandish cry for attention associated with other luxury cars. The car is a powerful, mid-engine roadster created by the German manufacturer.

If you want a great sports car on a budget, then opting for a pre-owned could well be the answer. A comprehensive pre-purchase inspection will help you to identify any immediate problems and to assess the overall condition of the Boxter.

So, if you are planning to buy or if you already have a Porsche Boxster and then it is always very useful to have problem guide. It will help you to take the appropriate maintenance care of the vehicle.


When you visit the dealer, before you even get in for a test drive look at the Boxster’s profile. And if you observe a slightly skewed profile, then you are probably looking at a broken coil spring. You can further verify your suspicions up by listening for knocking and groaning sounds whilst turning or driving over rough ground.


Corrosion is a common problem with the various wheels available with the Boxster and once it has started, the condition will deteriorate. Check for signs of damage, such as curbing and early corrosion, as it will mean the wheels eventually need to be refurbished.


The gear transmissions on the Boxster are reported to be of a high quality. But, this does mean that problems and issues will not happen. In the case of automatic systems, listen out for clicking and humming noises from the rear of the car.

And the manual systems may be affected by stiff gear changes, heavy clutch pedals and a clunking sound when powering down the engine. Be careful that all these events are serious warning signs and should not be ignored.

Air conditioning

It is common to find leaves and other debris becomes lodged in the vents on the Boxster. And if you do not clean them, moisture from the material will cause the radiator and air cooling systems to corrode. So, make sure to check the ducts to ensure they are completely free from debris.


Check the operation of the roof when inspecting the car to ensure it goes up and down smoothly. Problems with broken push rods on the roof mechanism are common, but they are simple and relatively inexpensive to replace. The other thing to look for is evidence of leaks, particularly from the rear roof drains which can get blocked by dirt and leaves, forcing rainwater into the cabin close to an electronic control unit.

Oil seals

Take a look underneath the bodywork of the Porsche Boxster. If there is a leak, then it is due to the degraded rear oil seal which allows oil to leak from the engine. This issue may seem small but you will need to remove the entire gearbox assembly and this may cost more.

Cylinder bores

Another common problem with the Boxster engine is with eroded cylinder bores, which can cause the vehicle to have low oil levels, sooty emissions and a tapping sound coming from the engine, alongside decreases levels of performance. However, the only way to absolutely confirm the presence of this problem is with a mechanical inspection.

Exhaust manifolds

An issue we are starting to see more of is cracked exhaust manifolds, which can be caused by heat stress or corroded bolts. Excessive engine noise, exhaust fumes escaping from around the manifold and loss of performance are all possible signs of a crack, which can be difficult to spot by sight unless you have the facilities to inspect the underneath of the car.

Cylinder head cracks

Even though this isn’t the most common issue, it’s worth popping the bonnet and looking at the
cylinder heads. You want to keep an eye open for cracks at the seat of the exhaust valves or around the spark plug holes, which could be extremely problematic for the functioning of the engine.
