I've spent thousands of dollars at this place over the years. I always felt that their prices are excessive but they're convenient to my home and they seemed honest and competent. Not anymore! $200.00 for a 50 cent fuse!!! My engine light was on. I told Plus One that it's for a system that speeds up engine warming in cold climates. Not necessary in SoCal but I needed it to power up to pass the smog test. They said it needed a fuse. Diagnostic Fee: $200.00 Dollars! I purchased four travel trailer tires from PLUS 1 PERFORMANCE at a cost of over $600.00. About 1,000 miles later one of them blew up on the highway in Texas! After being reamed for the fuse I'd had enough of these guys! I asked for a refund for the tire, THEY STILL BILLED ME FOR MOUNTING AND BALANCING! For a tire that blew up in two days on the road! And BTW not one balance weight on any of the tires. read more
