Already put a $500 deposit on it before I found this site. When I went to look at it the first thing I did was open the oil fill cap and ran my finger in it which isn't easy because of the plate inside. But when I pulled my finger out it had this gummy,coppery black stuff on it with what looked like little pieces of black sand in it. I showed the salesman and he didn't say anything. Asked for my deposit back and no problem. I feel sorry for anyone who buys that van.
