Offered a 2013 Sentra in trade of my Cruze.

I need your help.

I've been having lots of issues with my Cruze, and really wanted to get out of it. yesterday, I visited a local Nissan dealership, and they offered me a great deal on a brand new, 2013 Sentra.

Good payments, good interest rate, and good trade-in amount was offered. Told them, I needed to sleep on it. I also wanted to find out what you guys think of the '13 Sentra... 1.8L 6 speed manual, with Eco, Sport, Normal mode selections.
We just number crunched, and I really didn't get much more on the Sentra than I should of. I'm just looking for your opinion on weather I should do the trade, or wait for something else?

Thanks! You're advice will really help clear my mind!
