The battery is in back and it's the size of 2 big batteries and looks like something at an IT server farm! Jerry at the Castro Valley O'Reilly's spent an hour testing, then removing, and finally replacing my battery. A dealer would have kept my car for 3 days and charged me $1500 or more to change the battery. Instead, I bought a new $300 battery and Jerry did a masterful job installing it. And all the while, he was patient, friendly, leaving me feel like my buddy was helping me fix my car. I was given world class service and I'm super grateful to Jerry and the O'Reilly team in Castro Valley!

Found out I needed to check my coolant. Found the nearest auto place to me to avoid any damage due to prolonged driving. The staff were helpful and friendly. As I was purchasing the coolant they advised me to wait at least thirty minutes as a safety measure for the car to cook down and the coolant not explode from the combustion. A nearby Pupusas restaurant was recommended. How timely considering I hadn't eaten. I seem to be notorious for leaving the house on an empty stomach or having very little before leaving home. Anyhoo, Josiah an associate walked me to the Pupusa which was very close but I wasn't too familiar with the area. I ate, returned to the store and Josiah put the coolant in for me. Then I was off to make another stop before heading home. Thank you for taking exceptional care of me O'Reilly.

I tried Napa Auto Parts for the first time and had a really disappointing experience. The employee…read moreordered me the wrong part, then told me shipping wasn't refundable -- something never mentioned before I paid. When I asked about it, he smirked and dismissed me. I also bought a couple of products in-store, but later saw I was charged almost double or triple the shelf prices. When I pointed it out, I was told it was my responsibility to catch their pricing mistakes. On top of that, there were no signs saying chemical products couldn't be returned or that shipping wasn't refundable. Customer service eventually refunded me for the chemical items, but the whole experience left me feeling misled, overcharged, and disrespected. Definitely not the service I expected. Do Not Go Here

I didn't think I had enough problems in life so I decided to buy a 1988 Chevy Beretta GT yesterday…read moreto celebrate Presidents day in style. So these days I typically daily drive a Civic and so life has been very uneventful. No tows no problems - just fuel up and step on the gas. Yesterday I found myself ooogling CL classified ads to quench my quirky automotive interests and I found a nice modern classic with very low mileage and lots of deferred maintenance. Today I simply did some cleaning in and around the engine and changed the oil and filter. The oil that came out looked like it came from a diesel - black as tar. I got the house brand O Reilly type - as I don't want synthetic in such and old car and figure changing oil often is more important than having the highest quality oil. I was impressed to find the parts I needed - except the air filter - which I just got on eBay and will happily be on my way. I'm enjoying the unique exhaust note and when I fire it up I feel as if I could leave anybody in the dust. This is the GT version after all. Yes its great, its running better than ever. I cleaned the mass air flow sensor and I noticed higher MPGs immediately on the instant fuel economy reading in the all digital dash. This 37 year old car somehow still feels like a futuristic space ship. It was all done so fast - quicker than the dealer I suppose since I've got a good set up with everything I need within quick reach.
