Working on a post now, but I wanted to ask a question; while we're obviously going to find more gear during our journey, are we going to get any opportunities to tune-up or modify our vehicles? Like, say, if we got a new weapon, could we choose to enhance our firepower stat slightly?

No stats are fixed now, but you will be able to find more weapons, but the effectiveness is tied to your stats.
