These guys are amazing. I highly recommend Wilhelm's Automotive. Amazing customer service, they talked to me and even looked up my diagnostic codes over the phone to make sure it was a system they had access to (hybrid computer system). When they discovered how easy of a fix it was they forfeited charging me the mandatory system check fee, cutting my bill in half. Then they gave me several documents to help me prove to walmart the mistake they made so i was able to get a full refund of both my original bill with them and the difference on my bill with Wilhelm. Then on top of it a fancy thank you card. Just above and beyond service!!!!
