Cannibalization & Best Practice

What's the best way to deal with unintentional cannibalization? The site doesn't use 'blogs' per se. The product(s) are featured on vehicles with a 300-400 word copy. Naturally, when writing about the same vehicle, just with a different style of product, cannibalization occurs.

What's the best way to combat this without damaging the already good organic traffic we're getting? I was thinking of creating a 'landing page' that links to the vehicle specific 'blogs'.
