Process was pretty simple, but with a catch. I initially received a pretty terrible rate - much higher than was advertised on the Tesla website, and higher than I was even getting quoted by traditional car dealerships.
I emailed them back, and they quickly found another partner with a VERY competitive rate for my credit score/background. The only problem is that they had to do 2 more hard credit pulls in their search, which could adversely affect me moving forward (especially, worst case scenario, if I have to reject delivery and then re-apply for a loan when my turn comes back around).
