I live in University City and drive nearly 30 minutes out of my way to get to Champion Toyota.
The people are nice and extremely helpful. I know nothing about cars, and since they keep tracks of your vehicles service history, they print out the necessary services for your car once it's time to get them.
They also do an excellent overall diagnostics (tire pressure, fluids, etc) job with every service, even when you just go in for an oil change. You pay a premium over your neighborhood mechanic, but it's worth it.
Plus, while you're waiting, you can head over to the Shoe Warehouse (I think it's called), which sells excellent designer knock-offs of major shoe brands. I got a suade, shearling Michael Kors knock-off pair of boots for $20, which beats the real thing by about $300.
