Need help in making a decision on a Fiat Project car or a trip to Cali this fall.

The car- 1978 Fiat Spider, currently apart but body is solid and everything is with it. With selling my side by side, i dont have anything to tinker with when i get bored, so this would fill that gap for a long time (over half the time i had the RZR, it was getting something added to it because why not).

The trip- ~a week to 1.5 weeks, staying at friends places for some, hotels/airbnbs for the other and will be in LA and SF. Renting a convertible with a friend (he’s already going, but i may tag along)
