Get a 2011 or wait for a 2012?
Here is a model by model breakdown of my recommendations:
Jetta: No reason to wait for a 2012 unless you want an S model with a sunroof
Golf: Get a 2011 model unless you REALLY want a TDI with the new LED daytime running lamps
Tiguan: Tiguan is getting a facelift so check out the new 2012 model in person before making a decision. However, The 2012 gets 29 MPG!
CC: 2012 is nice but you can score 0% on a 2011!
Routan: 2012 model won’t be out till late fall and there are awesome incentives on the 2011s right now
Touareg: Too rich for your blood? wait for 2012 and there is a new less expensive (not by much) trim level coming
GTI: wait ONLY if you are shopping for an Autobahn package with the new wheels and LED DRLs
Jetta SportWagen: Get a 2011
EOS: its new and fresh for 2012
