Meh, so many vehicle models anymore look a lot alike anyhow. And things like pickup trucks... those vary even less with fewer brands to choose from.
Something that's very specific like, say, a Jeep Wrangler, might seem a little odd, but if they like the same model and color among the presently available options, so be it. Why should they not go with what they like best just because the neighbor also has one. Would only be weird really if the neighbor already has a habit of buying the exact same thing. (And in that case it's probably an insecure person who doesn't trust their own choices and looked to you as a role model for that.)
But, it's a plus to driving an older-ish model Wrangler, you just can't get them new anymore.
