Taking a long car trip and had dealer service center change oil and inspect van. They say the van needs about $800 worth of maintenance. At 53,000 miles the oil was changed and everything was fine.
At that point, it would be time to replace the transmission fluid. But you can have that done at a Jiffy Lube for under $100. Other than that, if you've continued with your oil and filter changes, you should be fine.
$800 is too much money for maintenance, especially for a toyota. All they do is 'inspect' the car.
