Known issues by generation
Each generation of the Grand National and GNX comes with its own set of known issues that can affect performance and value. The 1984-1985 models often suffer from turbocharger stem-seal failures, leading to oil-burning smoke—this is best addressed through specialists in Garrett TB-series turbo rebuilds. The 200-4R 4-speed automatic transmission, standard across all models, requires particular attention, with Bowtie Overdrives or Lonnie's style HD rebuilds recommended for handling boost. Intercooler clogging is a concern for the 1986-1987 models, while the age-related in-tank fuel-pump failures and MAF sensor wire cracking could affect reliability. Original-paint examples are especially prized in the collector community, with numbers-matching components significantly enhancing value.

Clean, original-paint versions easily exceed $25K in the current market, with Hagerty and Bring a Trailer listings providing robust auction comps for valuation. The GNX, due to its rarity, commands a collector market between $80K and $200K+, and can even reach $250K for documented examples at events like Mecum or Barrett-Jackson.
