1985 Buick Riviera Convertible V6 Turbo, former Florida car.
The owner was a car collector. He drove it very little since he purchased in 2020. It was last driven before October 2024.
When I tried to start in February, the battery was run down and a jump start didn't do the job.
Car was started in June. The visiting auto tech suggested a new battery.
Here is a video of this car in 2020
