Ive had a few problems with AC as well. Nothing huge, most of it was late shipping. I also think the discount is a joke. They wont give a set discount. Instead they say it varies by the amount of the markup on the item. For the most part they have great prices and they are the only one stop nissan shop that ive found. On a side note.. SLR has been great for me. I have made two orders from Spencer, and both have been very timely. Sometimes its tough to get him on the phone though.
