I recently had to replace the hybrid battery in my 2005 Prius. I had this quoted by Toyota as well as my local mechanic. Both quotes came in well over $3000 for parts and labor. RockAuto was recommended to me as an option. The reasons I'm so exceptionally pleased:

1.) The part was very easy to locate and purchase on their website. It included a 3 year/36,000 mile manufacturers warranty as well.
2.) I had this shipped direct to my local mechanic and it arrived earlier than expected. Packed in excellent protective packaging
3.) Returning the core was very easy to arrange. The cost to return using RockAuto's prepaid shipping was less than $45.00.
4.) I received an email confirming receipt of the core and my core refund is being processed.

Instead of a $3000+ job, my purchase of the battery and installation by my local mechanic totaled $1500!

Never will I hesitate to use RockAuto or recommend them to a friend. Truly exceptional! Thanks to the RockAuto team for the fantastic service you provide.
