Do I fix my RX7 turbo 2 (1987) or my Z71 (1995)

I have two cars at 15 years old, one is an almost running RX7 turbo 2 that I dumped 400 In already and my truck a 95 GMC Z71. My truck needs to be repainted but I runs well, and the RX7 needs a bit of work but will get running.

I don’t know if I should focus on Geting the RX7 running or the truck looking nice? Also what paint would you guys recommend for my truck if I do it?
