The ones you're listing were pretty much rally homologation specials.
Make enough to get into the GroupA.
Especially the likes of the Chevette HS2300. It was bitch in traffic with a clutch MADE for rally-line starts and not for pressing regularly in town
But I come back to what I was saying ... the GTi name was for a fast, light, responsive variant. NOW, it's only a title to a lardy, not very fast, not light, barely responsive car with a high price premium For the office managers girlfriend and not the lads in the office
Look around, back in the 70s every "fast lad" wanted and if had the moeny OWNED a GTi.
Now it's the bankers who've not managed to get the big bonusses
Shame, they needed to NOT use the GTi name for these ones.
THe other cars didn't re-use classic titles to sell the cars, isntead came up with "new".
( until that was Renault decided to revive the Gordini name ? )
