No diff or shock oil ...Yep...must be a ripoff...nobody with any sense would buy a buggy that dont come with oil.
I bought one just because I had some old diff lube left over from my Savage...and needed someplace to put it...that stuff is too darn expensive to throw away.
Besides I saved a ton of $$$ because the S3 DOES come with an airfilter

BTW...Saxton got a little out of hand with the rear camber spec...must have had his hands full with jelly doughnuts when he should have been measuring the upper link.
