Last month I gave my car to 3M car care, Arcot Road (Opp to FAME National). The outcome was good. I tried Foam Wash and waxing (don't remember the package name). But what I didnt like there was, The manager was trying to push me hard for an expensive exterior detailing package. They even gave me a demo of it which was good but I was not interested to go for it at that time since it costed ~5K. Since I resisted, the way he talked to me after that changed completely. His reactions were like "Why did you come here just for a foam wash and waxing which you can do in some local shop." Not only the manager but also two more guys there was also trying their best to make me got the 5K package. And when I finally asked them about the 3M carbon fiber stickers for the roof. The answer was just "NO" that too not looking at me. They did the same to few other customers too. Their attitude was bad like treating their customers as non premium if they don't go for a costlier package and make them feel like why not go for it so that I will be treated premium by these people. 3M nungambakkam and car cares are too good in that. Only during the payment after the washing is done they canvas about the other costlier packages they have and will say you can try that next time. But this guy in arcot road, as soon as asked him about the foam wash, he started to talk about the other package and didnt listen to me when I said I want only washing and waxing.
