Since last year for Bonneville was 2005, what are the chances taht 90 and above Bonneville will get into classic cars and will someday get a boost in its value.
What do you guys think?

Lots of models have come and gone without any added value. We dont see it happening to Oldsmobiles. And I doubt the Bonneville will fare any different. If someone has a 40th Anniversary Bonneville SSEi or a GXP in 50 years and kept it garaged and in showroom quality, ya OK. But the rank and file, their going to rust into history. It will be interesting to see how long the wrecking yards keep viable 3800 parts and */C'* around. If I were into keeping, modding, and racing them; Now is the time to stockpile. Soon enough they will be as hard as an old school Hemi'* to get your hands on.

I agree for the most part, but even that mint GXP that was left in a bubble for 50 years won't conjure up the same memories that the Hemi 'Cudas, LS6 Chevelle SS'*, and GTO Judges do. Those were iconic vehicles with storied histories and legends of a generation. Those are modern era vehicles that hardly anyone has even heard of. The right buyer at the right time, maybe. Overall, modern muscle/performance vehicles will never draw the level of collectibility that we've seen from the muscle car era. Only the truly rare tuner cars, Saleen, GMMG, Roush, or SLP will bring some money down the road.
IMO
