Thanks for the input everyone. I believe I've at least convinced them that it's an important thing to do. I also told them(to cover myself), that I'd use an OEM belt and tensioner and get an Aisin water pump from Rockauto.
The car really does run well, and I believe has the potential to run for a long time. It's been a good car to them.
kb01, the coolant was done at 90K, when the radiator needed replacing. As for ATF, it's only been done once, when it had around 35K. When I changed the oil on Saturday, I was quite surprised to learn that the ATF is still a red color and doesn't smell burnt at all.
