Buick wildcat and Buick Riviera

I have a 1968 Buick wildcat and a 1968 or 1969 Buick riviera. Neither of them run. Im not entirely sure whats wrong with them. The Wildcat needs a whole interior. Theyd be great project cars for anyone with the time and money. Both vehicles have rust, and need a lot of work. Looking to sell them together not part them out. They will have to be trailered as they dont run. Engine photo is of the Riviera. I dont know the mileage on them. $1500 Cash only for both, willing to sell separately They also do not have titles.
