I reached a compromise for my forum, now it just depends on if people use it. Since everyone's sig was just their vehicle specs, I added a custom profile field for "specs" and people can just go to town in there, then, I advised they just add a link in their sig for "Jeep Specs" so when they click on it the user just goes to their profile page and can see all their good info.
A few people are already using it, I know a lot won't, but even some is better than none.
