I wouldn't be too put off by the millage as long as the service history checks out ok and the price is reasonable
Just take it a good drive for at least half an hour and listen/ feel for anything unusual... being a VW mechanic he's probs tool really good care of it and used OEM parts
it's really down to you if you can live with a 95k+ car or it may be worth spending a bit more for less millage
Just to show you what's out there, I got mine in October last year... 56plate, 38000 miles, FVWSH for £8900.
But depending on spec (leather, xenons etc) expect to pay more
