I am building a new navigation system via breadcrumbs based on categories and sub-categories.
Example 1:
Having url like this:
http://mywebsite.com/listings-in-london-hatchback-car-for-sale-red-vauxhall
Having breadcrumbs like this:
Home Page > Listings > London > For Sale > Car > Hatchback > Vauxhall > Red
That Page has 10 red cars.
Example 2:
Having another url like this:
http://mywebsite.com/listings-in-london-hatchback-car-for-sale-vauxhall
Having another breadcrumbs like this:
Home Page > Listings > London > For Sale > Car > Hatchback > Vauxhall
That Page has same 10 cars but users may add in the future cars which are not red.
Example 3:
Having another url like this:
http://mywebsite.com/listings-in-london-hatchback-car-for-sale
Having another breadcrumbs like this:
Home Page > Listings > London > For Sale > Car > Hatchback
That Page has too same 10 cars but users may add in the future cars which are not vauxhall.
There can be similar situations for other categories. Is it bad practice ? Can it be the cause for duplicate content penalty ? What should i do for avoid any penalties ?

The duplicate content issue you are talking about is a filter and not a penalty.
Google will probably think all those pages are the same at the moment because they are so similar. So Google will only display one of them in the search results. The one it thinks is most important.
This is because Google thinks it's not in the users interest to see ten search results that end up showing exactly the same information. So Google filters out those duplicates from specific search results.
Over time the pages will start to become more unique, target different keywords and hopefully end up in the search results based on their own merit and not trample over each other.
Saying that...
Googles Panda update was about weeding out websites that have a high percentage of poor quality pages. If there is too much duplication, especially if other websites are using the same copy, then there is a chance that the website might trigger the Panda!
Another slight negative is that it creates more pages for Google to crawl, meaning it may take more time to discover new or changed pages.

Nope, I think it's fine with navigation like that, I doubt any duplicate content penalties could be give, just remove the breadcrumbs on product pages as it can be slightly annoying. Check out a good breadcrumb navigation best practice guide here. You can also check out the official 'Duplicate Content Penalty Demystified' guide here.
