Your definition of "epic" may be different from mine.
There is only ~1 page (50) of active vehicle FS topics, currently.
Half of those are locked.
Topic starters can lock their own threads, and
should be doing that.
If they don't, the thread will get tombstone locked after the 30 days of inactivity as stated in the rules.
So to sum up: Don't look at locked threads expecting them to still be FS.
The ones that aren't locked... are probably the same ones that still have a kijiji ad that you would waste your time clicking.
