Is there a realistic release date for the whole game? 
Check greenlight. It says late '13 or early '14. That’s all we know.
Hmm… What I have understood right that is too early… If the final car designer will be out late 13 I’d guess that the whole game would be close to finished Q3-Q4 2014.
Late 13 is more for the full car designer 
Also: Release is when its done. We always encounter stuff that can make the dev-time longer. My Guess for a complete Car Desinger would be End October/Mid November
Lol okay sorry! I just read off of the greenlight page
Thanks Guys.
Pyrlix, does your estimate include marriage?
Full Car Designer means you build the complete car. And a complete car includes an engine. Marriage is the next step on the to-do-list, even before things like interior choices or suspension tweaking.
I’ll go fix the Greenlight page, that was a very old guess at release date and it’s a bit too optimistic
