If driving less than 30k kilometers since Jun/07 had an advantage, that was not being able to get _really_ bored.
But the way I see LFS changed a lot during that time. From lots of pick-up racing to mostly league-oriented driving. I still join CTRA, but after two or three races I can't be bothered to drive anymore and just sit on the server watching and chatting.
With leagues is a different matter entirely. I really enjoy the process of setting up the car for the upcoming combo, trying different things, talking to/watching those I'll race against etc. And those last minutes before the event starts are very exciting.
Having a team with friends really help being close to LFS as well.
