I found this enginebay image on a carprofile at Minkara:
The car itself is an AA63 Carina with an almost stock 4AGE in it, nothing fancy at all. However, as you can see all stickers are on the inside of the enginebay and not on the outside of the car, like for instance on the fender as it is done a lot nowadays. Must probably be the influence of examples taken from movies like The Fast and The Furious…
This car profile is of an owner who at least owns the car since the early 90s and these stickers look like they are from that era as well. Look at the Option sticker: it’s from before they started doing videos as well! So I assume this is really oldskool sticker tuning! 😉
