Used Porsche 911 Cabriolet 2005 - 2012 reliability review

What should I look for in a used Porsche 911?

Despite being so easy to live with, Porsche 911s are still specialist pieces of machinery that require expert maintenance, so look for a car with a full service history from either a Porsche main dealer or a well respected specialist. If you’re buying the car privately or from a dealer that isn’t a Porsche specialist a few hundred pounds spent on a professional inspection is a wise idea, as an expert in the marque will be able to look for problems and quickly weed out any potentially troublesome cars.

The roof system itself should open and close smoothly in around 20 seconds, and be in good condition. Also check the carpets are dry. If not suspect blocked drainage holes inside the wheel arches as the likely cause. It’s good practice to clean these out every six months or so to avoid problems, as water ingress could also damage electronic systems in the car.

Rust isn’t an issue with 911s, but engine abuse can be. A decent specialist will be able to check how many times the engine has been over-revved, as well as trace the cause of any misfires.

Is a used Porsche 911 reliable?

For a car of its performance and pedigree the 911 Cabriolet is proving to be reliable, particularly in Gen 2 guise with its direct injection engines, or as a Gen 1 or Gen 2 Turbo. That’s not to say that faults can’t emerge, however, and it is important to understand that costs for parts and labour can be high due to the car’s specialist nature.

In terms of the brand, Porsche itself finished 15th of the 32 manufacturers included in this year’s What Car? Reliability Survey, putting it behind Audi but ahead of BMW and Jaguar.
