John Roberts Motors / Fraud
John Roberts Motors (Chevrolet Dealer) in Gunnison, Colorado was asked to change my oil and replace spark plugs. They checked my air filter and pronounced it "good". Three days later I discovered at another repair facility that they had left the (dirty) air filter cover loose and hanging in the breeze.
When John Roberts secretary called asking how was my service, I told her. The new owner called and told me that if I asked specifically, he would refund the portion of my bill related to checking the air filter. I declined to "request". He thought better of his position later, and reifunded the entire amount of the bill. I later found (at another dealer) that John Roberts' people had also failed to properly tighten the replaced spark plugs.
