The car is up for sale again, at $1,450 this time! I went and looked at them in person. The fit is poor, so probably not a dealer item, but I'm sure I could fix them. I looked up the VIN and it does not mention them. The salesman turned down my offer to buy the overriders. Does anyone want to buy the car? I'll give you $100 for the grille guard and overriders!

I also saw a W115 for sale with similar set. I want to know who made them!
