I really underestimated my Sonic upon purchase, thinking it was only going to be a good commuter. It has proven to be tenacious and resourceful in negotiating weather, cargo, aggressive drivers and marathon grocery runs. It also is plenty large enough for my best buddy and 120-pound fur-baby to go along on all runs, and still pack in the camping gear. The windows are power, and I keep things cool for him in back while I heat my own rear on the heated seat in front! Neither of us have to suffer for our conflicting metabolisms! Lol... I admit, I still miss being able to listen to my books on CD :( and I can't do that in the Sonic (digital only - which I still can't figure out how to use... lol), but the Bluetooth display and backup camera more than make it up to me, every single day. I named her Ladybug, and she has been adopted to this oddball family!
