Which of these two 2019 Shelby's would be better to collect?

[98SVT - was 06GT]

.......there is a chronological timeline period required for a vehicle to migrate through it's stations of being; from a new car to a used one, then somewhere in this unpretentious state if it manages to survive relatively unscathed and then down the road somewhere in time the populus happens to acquire an interest, and if that fancy proves great enough to outstrip the availability, it may begin to ascend in value. ....... 

There is also a peak where those cars begin to lose value as the collector base ages out. Most car collectors buy cars they had or wanted in their youth. The Model T and Model A are currently 2 cars that are losing value. There is a nice T Phaeton on Craigs list for $8,000 - been sitting 11 years. The family is selling it. 20 years ago it would have brought 2-3 times that value. I paid $15 for an A a couple months ago. about 6,000 miles on the restoration. Top quality stuff on a very good rust free car. Has all the trouble free driver upgrades - syncro trans, overdrive, real bearings in the engine, alternator (still 6 volt), pressure radiator, 16" wheels with period looking radials, etc.  5 years ago it would have been 20-25 grand.
