Dang, I just keep running into you
@jdmdc5teg06. Seems you're interested in all the same things I am for my rebel.
To answer your question, yes I've had a set in my rebel for test fitting. Here's the kicker on the rebel... You can't keep your factory covers. The two models are different and the reclining/premium arm rest isn't offered on the rebel trim at this point.
I had a limited set in hand and got a good look. It could possibly be done if you found an interior shop to match your leather. However, with factory parts you'll never match your fronts
that being said I haven't got a good look at trx covers! They also keep adding features to the rebel. think 360 camera and auto park that werent available until 2021, or even leather which came later as well. If they ever get all the stuff I want added I may be tempted to trade in. Until then you'll have to pick and choose what's worth the fight. Like those front vented seats haha. Or just give up the rebel seat covers and do a full limited swap. If I used my rear seats more that's where I would have gone with it.
