The name of the brand and car was stamped onto the side, in front of the driver’s door, in that stamped metal lettering. It was some cursive font. I don’t exactly remember what it said, and I already tried searching on my own, but I think it said corvette c2 or something like that. I may be misremembering entirely, but it was definitely <brand><letter><number>
It had 6 rear red taillights, rectangular in shape, oriented vertically, in 2 groups of 3 on each side of the car. Like -> ||| |||
The car was red (I realize this likely doesn’t help, but it’s here anyway), with a spoiler. It was either a convertible, or had no roof at all.
The brand logo at the front of the car was not standing up on an ornament.
When I tried searching, I just couldn’t find the taillight orientation at all, let alone the right car :D
It was fairly boxy and angular, which makes me think it’s a bit older.
If there’s any other details that might be helpful, ask and I might remember.
Old, new?
Oops, sorry, missed your saying kinda old.
Boxy/angular could be 70’s.
I think the Mustang idea because of taillights makes most sense.
