I am a little surprised by a few of the comments by members about this...

The seller (Silverball) is a honest all round good bloke.  I'm not going to speak (well type) on his behalf, but I think Mike (Homepin) has pretty much nailed it.

My best mate is a mechanic.  Runs his own business and works on average about 15 hours a day, 6.5 days a week.  The last thing he wants to do is work on his own car when he gets home at night.  He has a young family and all he wants to do is spend what little time he has with them.

I always joke as the radio in his car is not working, and it has not worked for about 12 months.  He complains about it and never gets around to fixing it. 
Is it because he is a sloppy mechanic.  NO. 

He is by far the best mechanic I've ever  seen and certainly trust him with my life and that of my wife to work on our cars without question.  It is that he puts his customers cars first, to (a) keep them safe and happy and (b) earn an income to make sure his employees get paid each and every week and put food and a roof over his family's heads.

Will he ever get around to fixing the radio in his car?  Most likely not....
