Possible to remove duplicates from a selectlist populated by json?

I have a selectlist that is populated by json. The issue I'm having is I get duplicates in my selectlist and I'm hoping I can remove them as the selectlist loads.

I have a fiddle to show you what I mean:
See Fiddle

The actual vehicles aren't really 'duplicates' but since I'm only showing a select amount of the supplied data (name and basic style) they appear duplicate in the select.

I came across juery.unique() but not sure if that would work... or how to apply it in this instance. Any help would be appreciated.

There are not actually any duplicates in your example.  

For example:
<option value="200420764">ATS Luxury 4dr Sedan</option>
<option value="200420763">ATS Luxury 4dr Sedan</option>
<option value="200420762">ATS Luxury 4dr Sedan</option>

While the text is the same, the value is different.

Notice this in your JSON:

                "id": 200420764,
                "name": "Luxury 4dr Sedan (3.6L 6cyl 6A)",

                "id": 200421837,
                "name": "Luxury 4dr Sedan (3.6L 6cyl 6A)",
Because the ID is the key and it is unique, using something like juery.unique() would not help.
You could use contains() like this:
if (!$('#newmodel option:contains("'+ String(data.models[i].name +" " + data.models[i].years[j].styles[k].name).replace(/ \([^)]*\)/, '') +'")').html()) $("#newmodel").append(option);

Open in new window
