Agreed with your comments on the Loh Brothers of AZ Master S/B.
My only ball of contention, however, would be the young Technicians (trainees from TOC or some automotive college, I believe) in the 3S Center.
1) Overly gung-ho. Why?
They unilaterally decided to tighten my handbrake cables without first consulting me. I wouldn't have any issues with that if they did a good job. Instead, they over tighten the cables which resulted in my rear wheels being 'sticky' even after having freed the handbrake. I requested for them to fix it, and they seemed unhappy. One of them even commented that the brake shoes will eventually wear itself out after driving it for a while. I told them a big NO.

I believe this is one of the possible causes for high FCs to certain vehicles which shared the same 'treatment'.
2) Another minor issue would be their effort towards cleanliness. What do I mean here?
Well I do believe that our Fortes are all brand new cars, right? As such, it would be great if we can keep our cars clean especially the interior, right? I mean, how'd you feel if your car seat was stained with dirt and/or oil smudges? I know I'd be

and

coz I'm aware that those stains are tough to get rid of.
My query would be, why couldn't the SC Technicians select a designated driver (whom would be the one and only guy/girl whom is not required to dirty his/her hands for the day) to drive the customers' vehicles? Or at least provide protective-seat covers?
I fully agree with the 2nd one. Noticed mine was also dirty with mud stains and a little grease. It was also earlier in the day, I spent some time cleaning the interior.
I thought usually the service adviser would drive the cars in and out and also the test drive. No?
