 I got a Sentra SR Special Edition (GPS, Bluetooth, Sunroof).The review that Edmunds gave this car was completely wrong.First of all, this car drives COMPLETELY Quiet and Serene.It's quiet and the Nissan CVT Transmission (Best transmission on the planet, hands down) was smooth and made no "groaning" noise at all and was serene.The reviews are correct that it does make a "clunk" sound at 30 MPH, but this only happens once when it's warming up because it's and ABS system check.Honestly this is the nicest car I've even driven, the interior is well designed and comfortable, it's very roomy in the front and back, and the MPG is great, 29 MPG overall. Way nicer than Honda and Toyota.
