someone changed almost all vehicles from Grand Cherokee Limited / Laredo / Overland / SRT8 from model name to extra info may I ask why? I always considered these words as parts of model name.

Yes I did, as it is mostly trim level / edition, isn't it?
I can re-change them back to the old name style if needed.
Several of them were already in extra info actually.

it basicly is, but not only trim level, it also indicates in most cases also the engine type.. Anyway i thought, it is part of a models name maybe some other opinion could help

Engine type is also often put as extra info (except for BMW and others where it is the model name, of course)

If you take for example
http://www.jeep.com/bridge/vehsuite.html?app=vehiclespecs&family=grand_cherokee&model=- undefined&zipcode=
Model is "Grand Cherokee", then you have different versions of it.

I would say it's part of the model name also.!
But I know it's easier to check for vehicles the way antoine has re-listed them.

What do you mean?

by searching probably - now they are all together - before were Laredos first, then Limiteds etc

That's why I put that in extra info for lots of cars actually : so they are sorted by year and not by trim level. And to see the full name, you can use the search page, and select "view as list" in the advanced search.
