Absolutely. I did. I had just under 60k on the 2010 Jetta TDI 6MT and considered keeping it until the wheels either fell off or the motor imploded after a long life.
Test drove the Passat TDI SE w/DSG. More room, way more room. More comfort, way more comfort. I liked the DSG too. And the Jetta was the only car in the past 14 years without auto climate control and auto headlights.
So I was suckered into the Passat TDI for room, comfort, DSG, same fuel economy and automated climate control and headlights.
If you are a frugal sort and under 5'-10", keep the Jetta because the new Passat isn't worth it. But if you can spare few $$, are taller than 6'-3" and think bigger is better (with the same fuel economy), than the Passat TDI is calling your name.
