Most JLs are short runs 10,000-20,000 with + or - 1% of the run for WL.
There are runs of 200 and 500 and those are very LE.
I guess to answer your question is to find out what model you are looking for and what you think you might get for it.
For example the HT Daytona and Z are very small runs but since they came from a very cool individual I would not sell any of mine that were given to me.
Fest castings are another small run and I personally keep the ones I buy except in rare instances.
To me all the cars are LE due to the small runs. Now I'm comparing these to HW runs where 250,000- 500,000 for Regular Issue cars is the norm.
I hope this helps a little.
