Not all 60 )))
Made some down payment and remaining through tesla loan, which was backed by Wells Fargo.
I don't see any risks of paying upfront. If something wrong will be with the car, they either fix it, or replace the car.. so don't see any issues why not to pay online. Dealing with checks - it's so old school.
By the way, do you know guys, that the US is the only country in the world that still uses bank checks... I am not saying that they don't exist in other countries, but people just don't use them.
