Mechanic in Stevi has the car, has permanent "family crisis", been 3 years. Any advice on what to do next?

Hi folks, The mechanic in stevensville who used to be a VW mechanic has our Mini. It's been 3 years and he has one family crisis after another, never gets the car fixed, puts it off. After years of listening to my husband feel bad for this guy (who is identified on Reditt as someone you don't go to because he with holds vehicles and doesn't do the work) I'm fed up. I figured out his shop, The Wise Westy, is now closed "permanently" but he failed to mention that to my partner. Do I show up with a tow truck? And the cops? All suggestions will be greatly appreciated - if anyone has dealt with this guy successfully I would really like to know how they accomplished it. We'd like the car back, even if it isn't running. At this point it seems a lot like theft. Sigh.
