I've be cautious of buying any former Rivian loaner. They seem to charge them all to 100% and that's not good for the battery long term. While there's less than 1,000mi, if its a 2023 its spent a fair bit of time just sitting, and if at 100% that's not good.
Sold my R1T recently when I decided to get a used R1S instead of the R2. Rivian offered me $48k for a 2023 Dual Performance Max Pack with 25,000 miles on it. Carmax gave me $52k.
Rivian's trade in prices are low and their price on used vehicles for sale is way too high compared to the rest of...
Looking I'd say compatible isn't 100% there, but this also looks like its only for Gen2, as it oesn't show up in the portal for me when I look at Gen1. Pretty sure this was posted previously unless this is Gen1 and I'm missing it now.
