Very responsive. Scott himself came out to assess the chronic problem I've have of the car intermittently not starting with sometimes 10 to 15 tries with the key. This occuring on a Saturday, even so the car was repaired and back to me the same day.Sunday morning we headed out to Denney's for breakfast confident the car would start. First try, no start. Second, no start, third try and it started. This morning (Monday) it started first try. So it looks like it's some more watchful waiting. :-) That's life. Someday we will get it.
