I think its a joke, all they are doing is an oil and filter change using non genuine parts for €139, They do not even visually check the brakes or what about balljoints and bushions. It is a home oil change that owners used to do in the past. And I am sure if there are any problems or you have any questions it will be I qoute (You will have to contact your main dealer) Its the same when you get four wheel alignment done in a fast fit centre, they will check it, try to adjust, take your money then tell your camber is off and you have to go to your main dealer. My advice is price your main dealer for alignment and if its a few euros more expensive go for it because they have technicians that can rectify it has a problem or give you sensible advice and have to have iso calibated equipment.
Also if its a cheap service your after, most main dealers do an express service which should match that price and do a better job.
