I traded a 2003 Mustang for my '11 SES Sedan and I can't really determine whether it was a trade down, up, or across...
There's negative and positive for both cars, but I think ultimately the Focus makes up for being a slow little sedan by being economical AND fun to drive.
So I'm going to say it was a trade-up.
2011 SES 5spd #006 >> SR #213
What other people think of me is none of my business.
