Just had an oil change and tire rotation. They left a valve cover off one of my tires, a little thing, I know, but it's the little things that make the difference, there was also a small grease stain on my seat. I can find another valve cover and clean the seat easily enough, by WHY SHOULD I HAVE TO? They are always trying to sell me new tires. The last two times I was in, they told me I need new tires, even though my tires are less than a year old, less than 20,000 miles (45,000 tread wear warranty), and are perfectly fine?!
