Seems impossibly cheap for a Riviera convertible at $1900. https://newyork.craigslist.org/fct/cto/d/1985-buick-riviera-v8-50/6331780202.html
Digital gauges and electronic touch (beep...beep....beep...) climate control. Nice options if they work!
I would have guessed this was an aftermarket conversion. Nope - an actual factory model, in the brochure. I'm getting old when I don't remember stuff like this. I AM guessing though that Buick farmed out the convertible process to maybe ASC, or some other company? Also, just noted looking at the brochure - you could get a 350 diesel in the Riviera, but NOT in the convertible.
You got it Krash, originally left the factory as coupes then were modified by ASC. Only available in White and Red Firemist.
I hated what happened to the Riviera in that movie - painful. Actually, there was more than one - they alternated between a 1982/83 model and a 1984/85 model. The older one got squashed.
