I predict the most desirable Corvettes in the future will be the ones that proudly display their chicklets.

 

Go look at prices for 1990's ZR1s - a very desirable car, imho - and get back to me. A $70K car that can be had today for high teens, low twenties in good condition.

 

It appears we run all the way from, "no C6 will ever be a collectible" to the Ron Follows and the 427 special editions will be the only collectabile ones. It also appears that 20 years is to short a time, 30 may be getting closer but could take even longer.
Will I believe that just like in the past the future will still have car collectors and that C6 corvette will be in those collections, they already are in some collections, National Corvette Musuem, GM Collection, and several large private collections have C6 models.
Some models will be more desirable that others for sure, but I agree that trying to predict which model that is and saving it for a huge amount of years with the hope some would want to buy it for a profit is not good money management. But on the other hand. Taking you corvette that you have driven and taken care of for years and paid for and saving it under a cover in the barn after you havr replaced it with a C7 or C8' has a good chance of being the barn find of the future. Just like the stok market and the lottery it's fun to speculate on what is going to be a winner, and since I am a car guy I would rather take the chance on a car than the stock marker, because in the end if no one other that you great grand kid wants to fix up and drive grand dads old car I will have still won

 

In 20 years, $30K has much better investment possibilities than a C6 Vette.
