This is a preliminary post.
I don't understand the Four nor Five Star rating meanings:
"Yay, I'm a fan" nor "Woohoo, as good as it gets". That said, details:
Mark has been straight forward about his problem solving technique and able to make reasonable risk assessments.
He's helping me with 1) 1998 Jeep Cherokee 4WD, 2) 1990 Toyota Corolla, 3) 1995 Toyota Corolla, 4) 2005 Toy Corolla, all of these are mine and friends' vehicles for past 2-years.
Even though only $100-300 problems have come along, Mark has been patient with us poor college students. I plan to maintain this connection and hope it blossoms into mutual reward :)
