PTune is a mechanic at 10 Admiralty St, #03-09, in Sembawang, Singapore 757695. It has a 5.0 rating on Google.
A good mechanic explains what is wrong in plain terms, shows you the worn part if you ask and gives you a clear quote before any work begins. A workshop in an upper-floor industrial unit, like those around Admiralty Street, is often a specialist or independent outfit, so it is worth asking what makes and kinds of work it does, such as servicing, tuning, repairs or performance work. When choosing one, ask what a service covers, how long the job will take, whether parts are new or used and what warranty is given. Regulars know that a regular service is cheaper than a repair, that warning lights should not be ignored, that unusual noises and pulling to one side are worth checking early and that in Singapore's heat, cooling systems and batteries need regular checks. Modifications may need approval, so ask first. Check the address and phone ahead, since upper-floor units can be hard to find.
