It was time for new license plates for a venerable car, but I couldn’t budge the old ones. Signal to the rescue! They also noted the Venerable One was due for an oil change and helped w/ that (with my OK) and did a careful safety check. There are some smoldering problems, and Avi explained in terms I understood (and sent pictures). I deferred for the time being – but I’m thinking about what he said. When I picked up the car, Avi asked if I had any questions. That doesn’t happen most places. Great experience.
