Really surprised at how nice it road

emptynest, 03/21/2016
2015 Chevrolet Sonic LT 4dr Sedan (1.8L 4cyl 5M)
Since owning the sonic I have had many people comment on how nice it rides. Even had one person say they want to get one. Very nice quiet smooth ride for its size. I bought this in 2016 but it was a 2015 sitting on the lot with a manual transmission, so I was able to get a terrific deal. 13k out the door for an LT sedan. Huge trunk which is important for me because my wife and I do … a lot of road trip vacations. Back seat space is pretty small with front seats all the way back, but not a big concern for us cause the kids are grown and gone. I am 6'1" and the seat still has plenty of room to go back. I was also considering the fiesta sedan and this car won out due to the better safety scores AND it was made in AMERICA. Only complaint I have is I wish the mylink system allowed you to mirror google navigation onto the screen. You have to down load their app for navigation and it is a subpar app. Oh well, just use the phone to navigate. Terrific little car for the money.
