Are you certain the "choppiness" you felt in the steering wheel wasn't the lane keep assist alerting you? My 18 Raptor is the first vehicle I've owned with that tech and it threw me off at first also, thought I had a blown out shock with only a couple hundred miles on the car.
No, it wasn't anything like that. I hit a bump and you could feel like a knocking through the steering wheel. Didn't feel right to me but the tires could have been over inflated.
As my self induced saga continues, I may make a deal on a Magnetic with Orange Accents tomorrow. They tentatively agreed to $3k over MSRP but they are giving me $54k for trade, so it's basically the same deal as the Lightning Blue. The MSRP on it is cheaper since it doesn't have the CF, Side Graphics or Bed liner installed. It does have Hood Graphics though. 802A, Dual Moon Roof, Bed Step, Tech Package, Orange Accent, Heated Rear Seats.
If that doesn't pan out, I think I'm just gonna chill, pay my registration on the GT350 and let a few months pass by before trying this again. Or maybe I'll just go back to buying a Lariat and calling it a day.
