Nowadays don't think there are many reliable workshops around, probably less than 10% of the market.
Since earlier of the year, have been frequenting a number of workshop & accessories shop to do up my car. Except for one workshop in Sunway & another behind pearl point, all the other that i have visited are full of shits & damn bloody hopeless. Here are my summaries (but sorry that i couldn't remember the names of the shops):
Accessories Shop (Just behind pearl point)
Went there to do my tinting; took them 6 fucking hours just to tint a mid size sedan, left my key in the ignition (power on mode) & cabin lights on for 6 fucking hours & in the process drained my battery. Jumped start by connecting to another battery but despite driving around for over an hour, just can't get my battery to charge up again. Can't start the following day & have to change a new battery.
Accessories shop in Pandan Indah (the one with a saga cabriolet in front of their shop)
Did my sound system there, other than the tuning part screwed up (spent half an hour re-tuning if myself) thought they are quite ok & brought my friend there to do up his audio system; pity my friend as he was stuck there for 8 fucking hours waiting for them to complete the job as they kept leaving his car & do other cars. Also, operates like AirAsia. Agreed on the price prior to installation but in the process of installing, will they you that you will need to add 1001 other things & the price keep shooting up.
Tyre Shop in Setapak
Went to get a set of adjustable fitted; the 'boss' was like a green horn & having to call to check for pricing on everything that i asked him. The worker (face like ci bai), work & attitude like the whole world owes him money. Later that night, heard some knocking sound at the front every time running over un-even surface / corners. Next day sent to another workshop to check, found out that they did not tighten the some of the nuts properly. Now almost a month later, something is not right with my front right as every time i turn left can hear & feel something hitting another. Need to send for checking again this weekend.
Accessories shop in SS2 along Public Bank
Went there to fit a set of alarm with push start; told me that they can get it done within 1.5 hours but ended up taking 5 hours. Totally screwed up the installation i.e. push start function can't start the car, alarm totally out & not able to sense the remote, installed the sensor antenna wrongly. After getting the alarm fitted, less then 5 minutes from leaving their shop, the alarm went off & subsequently stalled & unable to push start back. Luckily didn't disconnect the key crank so managed to start back & drove back to them. Later that night, can't lock my car at all as the alarm kept going off. Ended up have to send my car back to them the following day & get a new replacement unit. Got to resend there again to get a few other things corrected.
