I just traded in my 2015 Lariat on a 2020 Raptor. I was waiting for the 2021 redesign to come out and probably get a KR or Limited or maybe another Lariat. I really liked the idea of a Limited b/c of the motor. But then when I realized I could get a great deal on the Raptor (big discounts off MSRP in my area), I couldn't hold back.
Both the Limited and the Raptor are very expensive trucks with great engines. But when I think about what I get in the Raptor that I don't get in a Limited, I'm sooooo happy I pulled the trigger.
Also, on any new purchase, take a hard look at other options than the 0% deals because they usually want you to pay full sticker. Rates are very low right now anyway and you can still negotiate on the price. Just do the math and see what makes sense. I used my credit union (they are fantastic to work with), but even Ford offered me a rate around 2.5% for 66 mos.
