Trace, you are probably right, there is a mention in the loan offer saying offers are valid for 30 days. I thought that I had to make my order within 30 days of acceptance, like when you are prequalified for mortgages. When I purchased my previous cars, we agreed on the terms, make a down payment and you wait for the delivery. No surprise on the final price.
I emailed the credit analyst and ask for more details and he said that there was a disclosure on the website. Yes, there is a disclosure. However, there is no disclosure on the French Canadian version of the website that I used. It will be an interesting week of argumentation.
I also heard at Tesla Store today that they will revise rates at the end of February. Does it mean that you order a car and hope for the best until you take delivery?
