Looking for recommendations for 370Z service in Arkansas (Southern half or so)
 

I'm looking for someone to service my 2009 Touring. Apparently, none of the dealers in my area can figure out how to work on a 370Z. Eg,
Me: ... And service the battery when you do the oil/filter change.
Service Rep: Your battery doesn't require service.
Me: The 370s didn't come with maintenance-free batteries and mine needs some water.
SR: OK. We'll take care of it.
As you can probably guess, I had to add water to the battery when I got home.

I found the following dealers on Nissan's web site and would like to get some feedback on which one(s) might be trustworthy.

Orr Nissan - Bossier City, LA
Welch Motor Co - Pine Bluff, AR
Orr Nissan South - Shreveport, LA
Pete Mankins - Texarkana, TX
Riser Nissan - Hot Springs, AR
James Ceranti Nissan - Greenville, MS
North Point Nissan - Little Rock, AR
North Little Rock Nissan - North Little Rock, AR
