I have had a bad experience with S4S so I cannot recommend anyone to use them. I had a major service carried out by them on my Land Rover Discovery 3 in May, 2011 for which I paid £277.20. I was initially satisfied with the service received; vehicle was collected and returned on time and cleaned by the local servicing agent. I didn't receive any service check list indicating what had been done and any areas of concern I contacted S4S who said they would make sure the agent provided it. Nothing happened and a year later when my service interval indicator failed to show the next service was due I checked with the agent direct. He admitted that he had not been asked by S4S to do a major service, only oil and filter change and a visual check. I had my vehicle system scanned and found that the service interval data had been corrupted and would never show the need for service again without amendment. What was particularly worrying for me was that I had to have new discs and pads all round not long after following a noise from the brakes; I would expect a proper service to have warned of brake wear and action needed before the next service was due. I emailed S4S twice to query the work done and they did not respond. It was only when I posted a negative comment at ReviewCentre.com that the S4S managing director contacted me by phone. He seemed concerned and said he would check into my concerns but that is as far as it went. He just contacted ReviewCentre and got them to take my negative post down. It left a bitter taste and I would never use S4S again nor would I recommend them.
