The 1983 had the HT4100 (4.1 liter) engine. It is terribly under powered.
The diesel was no better.

Here is a clip from Wikipedia.

"In 1982, Seville offered heated outside rear-view mirrors with an optional rear defogger. Inside, a "Symphony Sound" stereo cassette tape system was available. The previously standard diesel engine became an option with the introduction of a new 4.1 L (250 cu in) HT-4100. This engine had a number of reliability issues, such as weak, porous aluminum block castings and failure-prone intake manifold gaskets. "

Head gaskets where also a problem.
