That being said, if you think it's OK for a mechanic not to use gaskets in things like oil pans, water pumps, thermostats, etc.;
and for a mechanic to give you a bill 33% or more over your initial written estimate, after giving you all kinds of lame excuses of why your truck or vehicle wasn't ready when they said it would be, then definitely take your car to these thugs.
You know one of the worst things about the Attorney General's Division of Consumer Protection? They only keep complaints on New Mexico merchants for a few years, then purge the files of their records. So when you ask them for information about a specific merchant, they only go back 3 years or so. That really doesn't tell you about the merchant's way of doing business over the years.
Don't take your truck or vehicle to just any mechanic in New Mexico. Do some homework and check on these people. Don't be influenced by them fixing police or sheriff's vehicles. They might do a good job on their vehicles, because they're afraid of them, but that doesn't mean that they're gonna do a good job on your truck or vehicle. Don't rely on the Better Business Bureau and the Attorney General's Office. You can rely, though, on AAA. Angie's List is a joke. A merchant him or herself can join it under another name and give her or himself a good review. If a mechanic is endorsed by them, chances are they can be relied on. But check your truck or car carefully when you pick it up. New Mexico mechanics often will keep a nut and bolt here, a rubber plug there, and so on.
