To start things off, I'd like to give a huge thank you to a good friend of mine, Cesar (@iamcesart), for joining forces with Visual Autowerks to fabricate this vent for the 1st Generation Toyota Matrix. I have been wanting these since two years ago. Unfortunately the people who were "interested" flaked out and this was with Billetworkz. To cut this review short, I just want to say that these vents really do make a big difference in terms of overall looks on the exterior of the hatchback along with its purposes. They're easily removed and easily installed so hurray for in-channel exterior accessories. For the summer time, I'd most likely keep them off just to keep the air conditioner running strong in the cabin, however for the winter I'll put them on everyday so I can run the heater without limits (if it even gets that cold, because California's bipolar weather lol). Also would like to thank everyone who participated in this group buy and made this happen for the community. I never thought this day would come especially since new/custom parts for this specific generation were getting closer and closer to being completely gone from the market. 2020 might not be everyone's year but it is for ours. Will definitely continue giving Visual Autowerks my business for any other fabrication services.
