Basically I usually just install as many mod tracks as I can for the sake of variety and a lot of them aren't great enough to race around more than once.
This track however I tested out quickly with URD's T5 Mercedes DTM car and it really is great. I love the high-speed double chicane at the beginning. Also another real treat is the mix of Static and TV Cams in the replay.
This track definitely has the re-playability factor for me
Here is my lap if anyone is interested:
