3000 miles later and I am still impressed with my Optima sx turbo. Driving a bit faster than Highway speeds 80-90mph it feels very stable, relatively quiet, it feels like you are doing 20-25 mph slower. If you hit the gas from 75-100 it feels like its running out of steam.
Sound system- Very good (however streaming is poor)
Poor (my 2011 Camaro BT was thousand times better) This cuts out and I have to reconnect.
Sirius Satelite radio still stops working under bridges and gas station where my xm in my camaro never failed.
Suspension-Feels great, not floaty
It was a great purchase. I would like to see a future comparision with the 2013 Nissan Altima 3.5 and the next Mazda 6
LED lights on the back are super bright (reminds me of a tanning booth)
Exterior design is phenomenal. (I do double take when I walk away)
Paranomic Sunroof gets people attention.
Fix streaming issue for bluetooth, make satellite antenna stronger and maybe switch to XM instead.
HID lights could beam a bit father. Offer sportier seats on SX, with more lateral support (Hyundai Genesis Coupe seats would be awesome)..
I agree with everyone here that the passenger seat should be able to go up. I sat in the passenger seat and it did feel super low.
I cant wait to change to quieter, more performance oriented tires. The tires that come with the car are noisy.
