Go with factory only, i have seen aftermarket installs thay look like crap and it compremises the intergerty of the car when you make a hole in the roof where there sould not be on, and what is a fuel ecomomy package never heard of that??

Agreed, stick with the factory sunroof. I would also recommend the SX and not just because I have one. The extras you get for the money are so worth it.

If you are worried about fuel economy differences there's a couple of things you can do to help.
#1. Watch how you drive. Your driving habits will have the most impact on fuel economy. Keep to the posted limit or less. Research has shown that most vehicles will get their best economy at about 70 kmh (45 mph). Watch that acceleration, try to take off in a smooth, gradual manner. If you're stopped at a long light, in a drive thru or anywhere you need to stop for more than 10 seconds, shut off the car.
#2 Keep your tires well inflated. If you keep them inflated to 35-40 psi instead of 30, you can reduce the rolling resistance quite a bit.
#3 At your first oil change, switch to full synthetic oil. It will reduce friction and wear, and reduce the load on the engine.

Good luck with the purchase of your new FORTE!
