I have a 2008 Lexus RX350, washer fluid is leaking. Had to take it to a new shop and they are quoting me $475 CAD for a tank which they say is the last in Canada and might never be manufactured again because it’s an old car. They are saying it will take three hours of labour and cost $877 including an oil change and coolant flush. I am worried that I am getting scammed as this is much more than I was expecting and the “last tank in Canada” is a bit of a red flag. Any advice?
