URLs changed on the website to more URL friendly:

Old link:
/cars/ford/display.php?Prod_ID=80717

New link:
/cars/ford /view/80717/fiesta

There is a script to redirect to new URLs. So even somebody clicks on the old link it will be redirected to the correct page.

Is there are any disadvantages of new URLs from SEO point? I’m thinking about old links from old link building campaigns.
