Most of the larger dealerships in my area (outside Phila Pa) have this type of dispatching service. It's touted as " we offer the best service, you'll get the next available tech from any one of our many dealerships."

This may be true- show up time is quick, I'll give you that- but the trade off is that the guy that shows up usually has no history with the machine, doesn't have the correct diagnostic tools needed, etc. But the biggest kicker is- the tech ALWAYS (at least this is my experience),ALWAYS seems to come from the most distant dealership in respect to where I need him. The mileage & destination charges can sometimes be more than the labor & parts portion of the bill.

All just smoke & mirrors, really jacks up the bill, & the lift doesn't really doesn't get repaired any quicker, at least IMHO.
