Love these guys. They are the best in town as far as I'm concerned. They have helped me with two different 4x4 Toyota trucks, and when I bought my last one used, they were patient enough and willing to give each prospective truck a once-over and refused to let me pay them.
You will probably be able to find a lower estimate at a lesser-quality garage. Don't do it. Go see these guys if you want a relationship with an honest no-bullshit mechanic.
