Our mechanical engineer is here to help the average motorist in Singapore with his series of thematic Q&A articles.

Last year, Porsche released a limited edition variant of its best-selling 911 sports car called the 911 R. It was priced at around £136,901 and only 991 were made. It sold out very quickly. Now the car is exchanging hands for triple or even quadruple its original price. Some are even believed to have been sold for over £1 million. This sort of appreciation is unheard of for a new car. So what is it about the 911 R that makes it so desirable? The reason is quite simple: of all the new 911 models, it is the only one that comes with a naturally aspirated engine and a manual transmission.
