I have been taking the service support of my car for few years now. found the service team to be quite smart especially their master mechanic.
Found the car lounge team to be helpful and try to protect the interest of both buyer as well as seller. they tend to be transparent in their transactions.
I benefited from the relationship with Car Lounge team particularly Basharat who seem to connect with all customers.
It can take a while for a window shopper to build rapport. my recommendation is to put in those efforts and one can reap the benefit when there is a serious purchase or sale of a car.
