I appreciate that you have put yourself in my shoes.
I would like to thank everyone in bmw-sg.com and vagsg.com for all the support and valuable advice including those sent via private messages.
It's heartening to know that people care for one another even though we may not know each other in person.
As the first session wasn't a pleasant one, the boss (SS Tay) was quick to offer me a "redo" session at no extra cost. I have dropped by FIRST AUTO yesterday for the remedy.
He was around to personally oversee my car grooming to ensure all the procedures were in order. It took 3 hours altogether compared to the 5 hours in the first session, a significant improvement in time. The overall result of the shine was also much better although they will not be able to rectify the meagre stone chips.
I have no doubt it was definitely a positive experience and I hope they will maintain this consistency in my next visit to First Auto.
