One of the few fully home-grown Irish cars was the TMC Costin, a sort of alternate-universe Lotus/Caterham 7 car. As fun as they look, I've hardly ever seen them in video. Until now!
This video is quite a slice of '80s Irish potato-booze-pie: a TMC Costin has the pole position, and it's even sponsored by Apple Computer. I'm guessing the Apple tie-in had to do with Apple's first non-US plant, which was in Cork, Ireland, and was quite a big deal in the early 80s. It's also fun to see that old rainbow Apple logo on the side of the car there.
There's some great 80s-era cars in that little clip besides the several Costins, but since it's St.Paddy's day and all, keep your eyes focused on those, ok?
