Known issues by generation
For the Pontiac LeMans Sport and GTX-J, key issues to be aware of include the notorious cylinder-head valve-seat recession on the 400 and 455 V8 engines when running on modern unleaded fuel. It's essential to consider upgrading with hardened exhaust valve seats, costing between $1,500 to $2,500. Additionally, verifying Muncie M-22 'Rock Crusher' transmission gear whine is important as it distinguishes these collector-tier models.

Lastly, extensive rust restoration could be necessary for unibody floor pans and lower panels, especially in salt-belt regions, making thorough documentation of your vehicle's condition paramount.
