I took my 25 year old 230,000+ mile Mistsubishi SUV in to address a couple of oil leak. The service technician told me they'd have to clean the engine off and put some die in the oil to see where it was leaking from, and then I'd have to drive it around a while. They didn't charge me for that. I brought it back and they checked it, and then he described all of the services they recommended , and why, and which were the most the most urgent, and what each would cost. He told me that he wouldn't spend the money on it because of the age and mileage, and because parts are difficult to find. I decided to proceed with what would be done now, and then they did the work. When I picked it up, he told me they had to do something else too, but they didn't charge me for it because it wasn't discussed. They are very honest, and they do excellent work.
