We are thinking of buying a NV3500. We are currently looking at a used 2013 SL model with about 48000 miles on it. Dealer wants 28990 out the door...has every option. First off is that a decent price. Also my main concern is if these things really last. Not real familiar with Nissan vehicles. Any help would be appreciated. Has anyone had issues with the NVP. Should I buy a new one vice a used one. Thanks.
