If you are still not sure about an auto parts sales site, take some time to research the company.
Do a quick Google of their company name and see what others are saying.
Pull the trigger and it's not making contact with someone or something and the gun produces a bright and visible arc between the electrodes and makes a loud snapping noise.
The typical worker should know the stock inside and out and should know exactly what you need.When customers bring home the wrong auto part, a return policy can make a difference.
So, make sure that the company has a wide collection of used parts and items such as batteries, gas tanks, radiators, transmissions etc.
However, it's mostly based on the estimated value of the vehicle as compared to the Kelly Blue Book so for example if you own an older truck that was in mint condition before you got rear-ended, the insurance company might decide the truck is not worth it to repair so they will want to total it.
