The spreadsheet is a mess for me and I get tons of errors and the rates don’t seem correct so I didn’t really dig through it.
Nothing unique about DCU for me other than it seemed popular with the Tesla crown and plenty of people posted their experiences with them so makes me more comfortable knowing they have the process down with Teslas.
Don’t recall seeing any reviews or experiences about Carolina Co-op FCU but 1.99% for 84 months is very good. Looking at it now it looks like they might require an annual $20 membership to the consumer council to maintain eligibility and does some things via snail mail. Their website definitely feels very 2000’s and not as polished, but that’s just me.
DCU was all online so far and I believe only a one time $10 donation required.
