that plan right there sounds good. I think the 300's were much more popular than the 500 series but I think those body panels and such will fit more than just the 300's so might be a decent demand for them.
They truely are beautiful cars in my opinion. Fit n finish was amazing and just the features were incredible, 1986 car with aluminum heads and overhead cam, full power seats with memory and power rear seat, power antenna, fully indipendant suspension all around, even had a first aid kit behind the rear seat on the "parcel self" along with another storage compartment and rear reading lights. OH and little angled footrests in the back seats lol, plus ashtrays in each back door with cigarette lighters. I always thought the gas door was neat too, nice flush finish and they put the hinge near the center so you could open it just by pushing on one side. OH and the famous headlight "windshield wipers" lol
Sorry for rambling, as you can tell I truely enjoyed that car lol.
