I went there to change the fuel filter and it took so long without telling how long. In/out log says 87 min when almost the shop was not busy. They told a very minor thing was was done same time for other customer. Later on my complain, the shop attribute to the part delivery and mud under of my car. From the parts delivery(26min, but it was earlier by my memory), it took more than an hour. Personally, it might not be a big problem such a long working hour, however, my son wait more more more, total a hour. Since previous day I heard it takes 20min(the shop claimed the shop did not say it). I have no idea the shop did not give only me approx. hour to work or generally the shop doesn't. However, I think it is a basic of service telling estimation. Does it take so long to change fuel filter ?
