Walk in went out. They came after hours and needed a hard start. From what I was told is this is a common oroblem, yet he didn't have part on truck. So he said they would call me in morn. They never did. I paid him $359.00. Called some body else they had it running in less than 10 mins and only charge me half of what de hart charged. Totally dissatisfied.. and satisfaction is not guaranteed!!!!
