How Long is Reasonable?

The scooter has been in the shop now for 88 days and I've almost lost all hope of ever getting it back.  The mechanic just seems to play with it now and then while working on bunches of other bikes at the same time, and I honestly don't know what to think.  That doesn't seem like a reasonable business model, but he seems to believe that it is and I guess it works for him.  Maybe he's saving me money on labor this way by putzing with the scooter a little at a time, but I'm frustrated almost to the limit of my patience.  I'm not angry at the guy because he's terribly likable.  But I'm awfully disappointed, and that might be worse than being mad.
 

When the dealership where I bought it ten years ago folded last year I was worried about finding somebody who'd be able to service the Piaggio, and then in turn I was thrilled when I took it to this guy who said it wouldn’t be a problem.  At that point it needed a new rear tire, a new drive belt and transmission rollers, a lube job, and something done to stop a small leak of coolant.  Three weeks later when I got it back I couldn't ride it after I brought it home.  The small leak was now a gusher and the thermostat wasn’t doing whatever it needed to do to cool the engine after it got hot.  I managed to get it back to the shop and it's been there now for the past 60 days, during some of the best riding weather of a typical year.

I've visited the scooter and the mechanic at least six times since I took it back and each time he encouraged me by suggesting that it should only take a little more time until it’s fixed.  But then another week or so passes, and little if anything gets done.

The problem is I really like the guy, but at this point I wish I'd never trusted him to fix my bike.  I explained when I first dropped it off that the old dealership took five weeks last year to play around with it, and added that I hoped it wouldn't be a similar time issue with him.  He assured me that it wouldn't be and I left it with him confident that it wouldn’t take too long, but here I am without my scooter for three months during prime riding season.

If you ask me for the name of the shop I’m not going to publish it here, nor tell you in a private message.  I am, though, going to direct the mechanic’s attention to this post and hope he’ll realize that he’s taken way longer than seems reasonable to have finished with my scooter and go at it until it’s done without keeping on putting it to the side for a few more days after every adjustment.

I just want to ride!  I think I’ve waited way long enough with the utmost of patience.  Please!  Get it done before we're at 100 days with me still riding  nothing more than a wish and a prayer.
