Can i Modify an AMC Gremlin to make it more modernized?

[jordan]

basically is it possible to fix and edit an old AMC Gremlin by making it quieter, improved a/c, better seating, and what not? ive heard how a gremlin drives and i swear they can wake up a neighborhood. or maybe im just overexaggerating haha. but yeah, if i can do all these, how much do you think all this would cost me? with an additional paint job if i can afford that too
