Documented, clean examples, especially those with original paint and numbers-matching components, are of significant value in the eyes of collectors, further solidifying their status in automotive history.

Known issues by generation
Common issues across the Grand National and GNX generations include turbocharger stem-seal failures, particularly for the early models, which can lead to oil-burn smoke. The 200-4R 4-speed automatic transmission often requires specialized rebuilding to effectively handle the increased boost from performance upgrades. Additionally, intercooled models may suffer from intercooler clogging, while other age-related issues include in-tank fuel pump failures and MAF sensor wire cracking. Original-paint, numbers-matching examples are critical for valuation, as they significantly enhance the appeal to collectors.

Auction results from platforms like Hagerty and Bring a Trailer further illustrate how well-maintained and authentic vehicles consistently appreciate, notably the GNX, which can command values from $80,000 to over $200,000 based on provenance and condition.
