I got my current RT from them (Marv Rose and son) in May 2004, and the car has so far proven to be a good one. However, I don't know how much he had to do with it - as he didn't see it until about 12 hours before I picked it up - but evidently he seems to have trustworthy connections, and/or is lucky.
One bit of advice concerning Marv and son (and is generally good advice overall): check the car over very closely before you take delivery - he does guarantee the car, but NOT everything. My experience wasn't totally good - I didn't find out until a few days after I picked up my car in Fresno that the soft top delivered with the car was trashed - holes from being stored in the trunk for five years and the hard parts wearing through, evidently. The car had the hard top on when I got it, and I neglected to unfold and fully check the soft top. Now, I didn't expect Marv to replace it - I *did* accept delivery and all - but I did ask him to help me replace it four days later - perhaps get a discount, whatever. I called him a couple of times and he said he'd try, but nothing ever came of it - I finally just paid $1600 for a new one through our local Dodge dealer. I'm not overly criticizing Marv for this, but just trying to make sure you know NOT to necessarily expect anything after the sale. In my case, note that everything else on the car turned out to be fine.
