First, there’s no reason to have a TRD version of the Avalon, but if you’re going to do it, maybe it should be a bit more than just an appearance package.
The Avalon TRD has no extra power and doesn’t have larger brakes. It merely just have a lowered suspension, some red paint on the calipers, bigger wheels, and a cheesy body kit. Oh, and red seatbelts.
The only thing the TRD version is successful at is to be less comfortable, and comfort is kind of the main reason you get an Avalon.
