I've used Barber Ford in Ventura. They replaced the turbo (under warranty) with no questions asked, even with an aftermarket exhaust system.
With my '02 F250, we tried to deal with Vista Ford in Oxnard. Bad experience. I made an appointment with them because of an oil leak at the bellhousing, which I explained over the phone. I also told them I had never been to them for service before. When my wife took the truck to them to drop it off, they explained that the appointment was only for the service advisor to look over the truck to see what was wrong, and THEN they'd make an appointment to fix it. Boneheads.
We finally convinced them to take it on the spot, and even talked them into a loaner. Within a day they had come to the conclusion that the crankshaft was probably bad, and that we'd need a new short block (under warranty). They went ahead and pre-ordered a new short block in case that the crank was the problem. A few days later they told us it wasn't the crank, it was just the rear main seal. Then they tell us that it will take a week to get in a new rear seal. So they can order a new short block just in case, but they don't think to order (or stock) a rear seal? They ended up fixing the engine just fine, but the service department management was incompetent.
