The only W-bodies that were destroyed under such program were the LQ1-engined cars. Everything else didn't qualify because GM built 'em to be so fuel efficient.
Its always amazing, talking to people who own Hondas and Toyotas, from even the early 2000s, about tune-ups, and being in sheer horror that the 2002 Accord still uses a mechanical distributor. I don't think a W-body was ever built with a mechanical distributor.
The government here recently cancelled the classic plate program, so its full freight on the plates if I want to keep mine past 30 years ($750/year w/discount). Still a great car, needs some paintless dent repair, and some new rockers welded on/primed/painted, but otherwise is immaculate. I bought a 7th gen Accord to 'replace' it a year ago, but still much prefer the CS. If the CS was in a wreck and I had to replace it with something identical (for insurance), I can't even find anything online for sale that's comparable. Heck, I can't even find a W-body CS sedan for sale on the largest used auto website in Canada at all.
