Took my '08 Toyota Tacoma here for an oil change and wash. Justin did a quick check before changing the oil and found that my oil cap was missing (apparently the last place I took it didn't tighten it all the way) and my battery was loose (probably just from off-roading). Since he couldn't do the oil change because of the missing cap he topped off all fluids, reattached the battery, and sent us through for the free wash. The only thing he charged for was the replacement battery cap ($6).
When my new oil cap came in I stopped back in for the oil change. I also needed a new air filter - no surprise there - it hadn't been changed in a while. By the time all was said and done I paid $65 for the oil change, air filter, and free wash.
They were pretty busy when I stopped in the second time, so it took about 45 minutes, which I think that's a reasonable amount of time given experiences at other places.
