I changed my posting with a quick price check. The F250 Lariat sells for about $15K more - $85K! It's the F150 Lariat that sells for around $70k and some change.But the payload and towing of the Rivian R1T are right square in the middle of F150 / 1500 territory, yet it remains more expensive than an F250, similarly equipped. It's only fair comparison might really be the V10 SRT pickup that Dodge discontinued a decade ago.
You're going to have trouble convincing me that any purchase of the R1T is for any reason other than show or giggles, similar to nearly any high-HP vehicle.
