Seems like No duration value is valid for Classified Ad, Car listing

Hello, I'm trying to list a Car as a classified ad listing, using the AddItem call, I'm closely following the sample [here][1] However, seems like no valid listing duration is valid, from Days_1 to Days_30 to GTC, also, using GetCategoryFeatures for The category I picked doesn't seem to return anything useful on the ListingValues node, (basically all I get back from this call, with many different options and categories is: ``) which doesn't help on finding a proper value for this call. This is the full call I'm Making:

   Unused and unopened within 14 days. By unused we mean not used. Not suitable or I changed my mind after I used it will not be accepted. If used we will not accept a return except where the item is faulty. If a returned faulty item proves not to be faulty or has been used or set up incorrectly, then item will be returned to the sender at their cost. A full refund will be issued within 3 days of receipt of the item (but not the postage either way). The method of refund will be a reversal of the original payment. Paid by Paypal, refund by Paypal, paid by cheque refund by cheque, etc..

Thanks for your help! I'm really clueless about this one, been listing through the API for over a year and never came with a strange issue like this. [1]: http://developer.ebay.com/devzone/xml/docs/Reference/ebay/AddItem.html#sampleclassified
