Benchmark saved me a trip to the shrink.What I thought would be a stressful day, hundreds of dollars in repairs and a missed dinner reservation for Valentines Day turned into an amazing day.Long story short: I just began a new job in Newark. I spent all of my most eyes on moving expenses so I was low on cash. It was the day after a major snowstorm so tow trucks were arriving late and several car shops were closed or couldn't work on my car

I would like to extend my thanks to Rich and Don for quickly diagnosing my daughters Toyota problem. It was more severe than any of us expected. Your shop was right up front with me on my options since we are so far away. They kept our vehicle save and secure for over a week and never asked
