We recently bought our second Toyota from Don McGill.
We recently bought our second Toyota from Don McGill. The first was a 2020Toyota Avalon and the second was a 2024 Toyota Crown. The first purchase went off without a hitch and we were very satisfied. The second car (the 2024 Crown) was purchased and delivered on 12/29/2023 with only one key FOB; I was told me I would get a second key FOB in six months. I subsequently talked to the service department; they promptly ordered one and I received it one week later. I do have an issue with the title department. My credit union is threatening to raise my loan interest rate if they don't receive the title. The only way to satisfy my credit union is to explain the process which I do not understand. The dealer should be more proactive in ensuring that the sales process does not end with delivery. My credit union still hasn't received the title. I am forced to keep calling which shouldn't be necessary.

Gabriel walked me through every step, answered all my questions clearly, and even followed up after the sale to make sure everything was going smoothly.
