Dealers have tried several different ways to represent other manufacturers products within their websites. you might find these examples helpful and one of them may work for you.
1. Target added other manufacturers products to an existing product category.

2. Graphic office created a new product category and created pages for each manufacturer:
http://graphicoffice.com/products/category/commercial-flooring/
3. Some dealers prefer to just create a section called: Other manufacturers and just list the MFG’s and link to their websites vs creating product pages

http://www.kyserofficeworks.com/other-products/
If you went with option 3, you could also create a text module on your homepage with the verbiage that you have below. That module could bring people right to the “other manufacturers” category/page.
