You don't mention if you are shopping for a vehicle or just parts, I'm guessing the latter.
I'd steer clear of John & Phil's Toyota in Corvallis- they were consistently about 10% higher than list, or the prices at Lassen Toyota in Albany, on parts I tried to buy there. They would usually match prices that I found on the web or in Albany though.
When I pointed this out to them they acted ignorant of the fact that they seem to apply a "yuppie surcharge" since they are in a generally more affluent town.
We bought a Subaru Outback there, got a decent price by playing hardball, but the salesman was kind of a ****head. And when we had their service dept "fix" the right pull on it (brand new) they didn't do a damn thing to it. I would have been back until they got it right, but we moved shortly after that.
Long story short, I won't be dealing with John & Phils any time soon...
