The owner of the local Renault dealership lived a block over from us when I was a kid, and his son and I were good friends all through school. He seemed to have a different demonstrator home virtually every night! I saw plenty of 1:1 Renault 17's back in the early to mid 1970's. I thought they were pretty decent looking cars, looking not at all like this Matchbox with it's Gremlin-esque styling. The car he had on his lot that I remember best was a Renault 11 that had been converted to a pickup truck! It was painted metalflake lime green and wore the lettering "Official Pace Car, Islip Speedway".
To make this Matchbox more realistic, you'd have to ditch the 5-spoke rims and replace them with a set of 3-lug wheels!
