I think it would be fun to have something like a sub-title under your screen name that reflcted the status of your car at the moment. I'm sure it would be more work than reward, but imagine if you could go into your profile and select one of the following to be displayed under your name (but above member since/donating member):

Current status: (pick one)
*optimal
*being tuned
*needing tuned
*technical difficulties
*terminally ill
*dead
*got rid of it

It could show up like this (only not such an obviously hacked photoshop)


I'm sure this would require a shitload of work, so I'm only mentioning it for some night when someone is suffering from one too many Jager-Redbulls and can't sleep.
