Help - stranded near Cahors!

Anyone know of a car repair garage near Cahors (I'm actually near Prayssac) that will actually DO something to repair my beloved Peugeot 405 estate - even if it's to fit a replacement engine. So far I've had it transported to three different garages (including - currently - the local Peugeot dealer) none of whom evidenced the slightest interest in doing anything despite taking it in in the first place!

Being stuck in the boondocks without transport is NOT funny.

Anybody got any advice, suggestions or - better - the name and number of a reliable mechanic?

Thanks all
