Auburn and upscale Replica cars

Does any one review the best Replica cars. I think some are maintaining and
possibly increasing as if true collector cars. Is there a way to determine
which brand may be a good investment? I am interested in the Auburn Marque
and have been of the understaning some manufacturers models are more
desireable and collectible, such as the Glenn Prey models. If this is
true, how does one determine which cars are built by Glen Prey? What makes
the Prey variety more desireable? Where do you find them for sale? Is there
a marketplace? [dickschulz@charter.net]
