Not in RI, but East Freetown Auto Salvage in MA is like that. I've gone in there for a few things in the past and had good luck. I haven't been in a while though, so I'm not sure of the number of Jeeps in there.
It's set up nice, all the vehicles are in neat rows and up on steel stands with the wheels removed, so it's nice and easy to get at stuff underneath.
I was going to head up there today actually, but then decided I didn't feel like laying in the snow. (I'm looking for a V8 tie rod and steering gear)
Not far from you is Smith's Auto Sales RT 32 N.Franklin,CT 800-843-4236 they are right on Rt32 Sign out front is for snow plows but down back is a JEEPERS Paradise From MJ to J20 I was up there one day driving truck and my boss said I would have to wait for some product to be ready couple hours and I came across this place I told boss I died and went to JEEP heaven and should call me in couple of hours to get me out of there
