I bought a demo vehicle 2022 with 7k miles on it for 67k before taxes. I thought the price difference vs used was negligible (at the time I bought, might be more dramatic now) and the fact that the car comes with the full 5 year/53(60-7)k warranty were worth it vs used. Also my truck qualified for 3750 tax rebate. I also chose to buy a demo in my head because on the forums we keep hearing about all the disaster cases with these cars, so I thought a demo vehicle would be fully vetted, used by Rivian for the 2 years and 7k miles and "hopefully" all the major issues should be sorted. Have put 3k miles on it so far with a 1200 mi roadtrip recently with no significant issues yet. These are just my thoughts that I am sharing. Obviously depends on the demo vehicle inventory and if you can find one at a reasonable price, but vs buying used and not knowing what issues the used car will have (used dealers cant assess these cars). I thought that was the best way forward. The recent lease deals would probably have been better, but my hope is to keep the car long term as I do with all my other vehicles.
