This story is so similar to a tale about my brother and a TR6.
He did the same thing, as he thought he had found a good trust worthy mechanic to do similar work as our friend above.
Money was handed over and yes he did a moonlight flit with the car and changed location.
What the little toe-rag never banked on was that we tracked him down. We turned up at the new location and went into the workshop to find him and the car (some what dismantled).
When we put the question to him 'why did you move and why no phone call? his reply was 'well that's how it is and what are you going to do about it?
I don't think that he was expecting my brother to slide him up the wall by his throat. Needless to say that we left the workshop with the car on a trailer and a refund.
This is not such a bad ending as our friend with the Morgan as we got the car and money back, it's just a shame that these people are out there taking advantage of others.I hope all goes well for our friend.
