I was under the impression that all Allison front engined cars were based on a Nissian. I’ve never heard of a diesel version till now. It’s a really nice car but that’s a nice, I mean high , starting point too.
Can’t imagine why anyone would build it diesel. Maybe a TDI VW or Mercedes… but a Chevette? An ’80s US diesel car? Everyone knew those were junk even back in the day. They were junk compared even to the incredibly junky junk that normal gas powered cars were then!
