Right, when i bought my Zed, it was all serviced at this one nissan garage, i phoned them up with regards to the service as the seller had it serviced two days before i went to pick it up and just wanted to make sure and be notified of any problems, they could tell me everything that had been done to the zed and all replacement parts, even down the to the wipers, i know mine has had a ew drivers side window motor, bout it really, Go give them a bell and see what they say ? ? ?
