He claims it runs; the motor and the road wheels would almost be worth the price. Unfortunately there isn't a lot left of the car; and because this is the "stepchild" Rivi, it'd be a tough restoration to get anything out of, there's no meat on the bone.
Almost all the Rivs I posted from the Left coast look like a family of raccoons have been living in them
Raccoons love Rivieras. Makes them feel more exotic when they sleep during the day. I don't see a console, so maybe a shorty was in there. Those look like legit 70 big car bucket seats. I always thought about buying a 70 Electra convertible - which I believe only came with a bench - and putting bucket seats in them and a shorty. Those BRW are likely 15 x 6 and obviously big bolt pattern. 455 looks original. I suppose it's a $500 car. The guy just wants it gone, wants someone to do the hard work of extracting it.
The car is located in the sierra foothills. Lots of wildlife in those areas. One of the last regions in northern CA where you find car hoards.
