My favorite are people like the people on this site. People who are currently modding. It might take awhile for them to post their next mod but its better then the huge instagrams of totally decked out cars that are "finished". Those I look at once and move on.
Some ST owners with instagram go a little pic heavy of their car. But I guess that goes with any car owner. I like pictures of the outside but when you start to post like 2-3 pics a day it gets old. There are some good ones out there though.
