In 2012, I had my Pioneer Head Unit, amp and speakers installed into my 2nd hand Vios. Till today (touch wood), they are still working well..
So far, this is the best accessories shop that I've been to.
Previously, I went to 2 reputable accessories shop to fix my air con led lights, but both shops were unable to solve my problem, told me they need time to source for leds.. Even my cousin who claimed he has "Lobangs" Also failed to find the spare parts.
The moment I stepped into Vim Auto, my problem was solved within 10 minutes..
Prices are reasonable. Alex is friendly, best of all, his workers are humble.

Bought a set of sound system from them. Was told that if i change car, alex will charge only 80 bucks for removing and installing to new car. Went back few months later, as i changed my car. He told me that's additional charges as the wires need longer and etc. I felt cheated as this is not what he said before. I will never go back again. Is just waste of money and time. End up i did it at JB. Which is cheaper and better.

12V wasn't working. Super prompt service by Alex. No waiting required and problem was fixed in seconds. Best of all - FOC.

Workmanship was average. And workshop can only accomodate 2 cars at most. If you have to wait be prepared to park your car a distance away.
