$31.61 after tax for a basic oil change (I think up to 5 qts). Really quick service - in and out in about 25 minutes.
They noticed that my friend's headlight was out and offered to fix it for $19.99 parts & labor...and also offered the advice that it was cheaper than a $40 ticket. I asked them how much they were charging for the bulb itself but they just repeated $19.99 parts and labor. I totally understand though because when you bring your car to a mechanic you're paying them for the know-how and not just the parts.
However, I know how to change a bulb so I declined their offer and just went to Autozone and bought a bulb for $11. That said, I quickly learned that trying to change a headlight bulb under the hot AZ sun w/ my glasses slipping and getting grease all over my hands wasn't the best of ideas... so we went back to the house and I changed into my contacts, let the engine cool down a little and then replaced the bulb in about a minute.
If you mind getting dirty, can't use youtube or the car's manual and aren't by an auto parts store then perhaps the $9 service charge is right for you. Otherwise, come here for the quick oil change and save yourself some money by changing the bulb yourself.
Also, my friend didn't have a coupon but apparently they have/may send out coupons to the local area so check for their coupons when you bring your car in.
I gave them 4 stars because of the efficiency and because they seemed to be genuinely nice. They also have a nice air conditioned lounge, with a water dispenser, coffee, tv, and magazines for their patrons to sit and relax while waiting.
