Local Auto Parts Stores:
Monument Auto Parts - Knowledgeable counter help, good selection of weird parts, Red Line dealer, name brands, they know what I'm looking for even if I don't know what it's called. And they have some old stock in the back. Invaluable for us old skool guys. They even have speedo cable lube!
Kragen/O'Riely's - Not enough sales people to man the registers. [censored] parts. OK for wax and stuff you can get off the pegs on the wall.
Autozone - Not enough sales people to man the registers or parts counters. [censored] parts. OK for wax and stuff you can get off the pegs on the wall. My oil filter source (Bosch).
Walmart - Shelves are usually bare. Good for oil.....if they have it. My Pennzoil source.
NAPA - Lots of [censored] regarding why my parts didn't show up and how they reserve the right to sell my warranty replacement starter to someone else if they happen to make a sale prior to me getting to the store that afternoon to pick it up.
Online:
Rock Auto - No issues, they call if there is.
Asian Auto Parts - I buy all my OEM Honda/Acura parts from them. I don't pay full list, they're just up the road in Sacramento and most parts are two days away.
Summit and Jegs - Good outfits and good tech support, but "Made in China" is starting to invade. I like Summit because they have a warehouse in Reno; parts are two days away if they don't have to come from Ohio.
Auto Barn - They have weird stuff that I'm looking for.
Susquehanna Motor Sports - For all my lighting needs.
