They are top notch. Mark Jr. is knowledgeable, competent and honest. I went in with several issues, thinking a couple of them were related. Someone could have easily told me that they indeed were and charged me a hefty price to "repair", but Jr. told me what the real issue was and provided a very inexpensive fix. In this day, it seems so difficult to find a mechanic who not only knows what they are doing, but primarily makes you feel like they aren't ripping you off just because they know many car owners don't have the knowledge and ability they possess. The folks at Mark's are good doodle and I'll be giving them my business from here on out!
