Body would need careful checking alright.
Antenna isn't a factory-fit - that's a raise/lower switch behind the gear selector (many European cars came without one), and it seems that it was (mistakenly) placed it where previous years 116s had theirs (front >'75, rear from '76). My '76 had none, but it was drilled and placed at the rear, where there is a factory electrical plug for it.
It's a '76 because it has K-Jet (first year), but has the thinner steering wheel rim that was thicker from '77 on.
No cruise or tacho, but it does have leather, electric windows, aircon and a sunroof (all extras in Europe).
The colour isn't for everyone, but if the body is genuinely good, and everything works properly, then the price isn't bad.
