I'm looking for a new car, I fancy a Golf GTD or Seat Leon FR in diesel.

Arnold Clark have taken delivery of a couple of dozen Seat Leon FR's on 2015 plate. All of them are sitting at between 33-38k. I've been to see three of them. None of them have previously had a service until going through the Clark's workshop in preparation for the forecourt. Thoughts? Should I avoid? They should have had a year one service at 20k.
