In my opinion restomoded cars will one day go out of style while stock looking cars will always stay in style because they define a year in history.
This statement is a true one IF the restomod owner chooses to leave the car untouched after finishing it with whatever styling cues are popular at the time. Since style cues or, dare I say it, "trends" evolve, so must a restomodded car to remain FRESH looking. While, I can agree that a stock resto can be considered done once and for all, restomods need constant updating. If the owner chooses to go that route. To each his own I say.
My car has gone through three different "looks" since I turned the first wrench on it in 1980.
But what's old is new again and eventually the older styled builds come back into fashion especially when found in a barn or a field abandoned someplace. Cars with straight front axles, jacked up a mile in the air with Cragar SS wheels, ladder bars and metalflake or lace paint jobs are all the rage with the retro crowd right now.
