Hi, I've been offered to buy a car which is allegedly Chevrolet Nava from 1977. Then, I researched a bit, googled it by info I received but never found matching photos of car I saw. Could you please help me identify if that's the model (even a make?) I've been told it is?

It looks like it, but you can run a vin check if you have the vin number.

 

Well, I owned one for 23 years, and as "Old Chevy" says, it looks like a '77 but - but since it's been customized as a "Limo" it's difficult to tell. It could be any 4th Generation Nova 1975 to a '79. The '79 had square headlights, so unless yours was changed I think it's safe to say it is not a '79. The '76 - '78 all had the same grille unless it was a Super Sport or Rally which I doubt yours was. The dash looks like my '77 when they went to round gauges. I think its safe to say it's a customized '77 - but again the VIN is the only way to know for sure.

Never saw one extended like that. With a 3-spd stick, yet!
