When I logged into oly a couple months ago, first vehicle I bought was a quilin and noticed it had doors, then right away, got into a fight with very little cover. Those doors saved my life, and made the fight actually fun. Instead of getting sprayed down in a field, I was able to move around the quilin and defend myself. Big +1 for that, and think the price should be raised a little.
For houses, honestly, I’d say lower it to 3. Having 5 houses is nice, but is it necessary? With 3 you can have 1 spawn point house, 1 money making house, and the 3rd could be anything else or one of those 2. I know many people won’t like it if this is implemented, but you can’t deny the fact that it will open up houses, and therefore, potentially keep new players around longer.
