That question was probably been asked million times before, but i coulnt find an awnser. How can i replace the old vehicles without having to do it manually (which sucks)?

You can replace vehicles (by type)
See this wiki article: http://wiki.openttd.org/index.php/Replace_vehicles

And you can autorenew vehicles (by age)
See this wiki article: http://wiki.openttd.org/index.php/Autorenew_vehicles

And: Some people would have told you to search the wiki on you own. It's really informative!

The wiki has definately come along way since I first used it...
