I brought our car today to the dealer’s shop for regular maintenance. It’s good that they preesnt the invoice before doing the job. I noticed 3 things – 1) additive to windshield cleaner, 2) brake sound remover, 3) anti-barcterial for aircon. It seems to me that those extra charges are not really needed so I requested them to be removed. The total of those extra charges amounted to $40. That’s how much I saved today.
