Hey Peter,
I'm glad you came out of the accident realitvely unscratched! I haven't had the best of luck from Arlington Nissans service department, but I only had limited exposure from the dealer side. I purchased mine from Gerald in Naperville, I had a pretty good experience with them. Although I got kind of screwed in the finance department! The dealership up in Libertyville, well let's just say I knew more about the xterra than the dealer did, but that was almost 3 years ago. Good luck with your hunt!
