Toyota is expensive to buy parts for, and you need their tech to access codes or make changes. Unicarrier is most friendly to access. It is basically a Nissan, with Cat and Mitsu mixed in. Under the hood, they are all the same, so aftermarket parts are readily available. Hyundai is also very user friendly, and comes with very good warranty. Stay away from Chinese brands at low cost. The parts are incredibly expensive and take forever to get. All unicarrier and Hyundai parts are readily available in the USA.
