Help! Could anyone recommend a *local* mechanic that may be able remove an oil sump plug with a rounded head? Car is a Vauxhall Insignia with a 13mm plug which had been nicely rounded off by the previous owner/service garage.... Unfortunately I didn't check it would come undone before putting engine flush in, so can't drive car more than absolutely necessary. I have new oil filter and oil ready and can get new plug if it helps. Need car roadworthy by Thursday!
Many thanks for any suggestions :-)
