Just personal opinion, but I think the 70 and 71 cars were the best. They got all the mechanical upgrades - basically switching over from 122 to 140 sharing, but still had the slightly more bespoke interior. Which I guess boils down to the door handles - the later years had 140 door handles on plain panels, the 70/71 had the molded swoop like the earlier cars. Plus they had neater looking wheels, vs. the plain steel wheels shared with the 140 on the 72-on cars.

And they got the full 130 hp B20E, not the slightly neutered for emissions B20F. And the coupes didn't have a bulky complicated folding rear seat (designed for the ES, but used in the coupe too). And although they had retracting seatbelts (nice) the pods stopped the seats from reclining all the way back (I guess that's fairly unimportant, really).

But really, there aren't any stinkers in the whole production line. Some people like the earliest Jensen built cars. I happen to like the D-Jet injection and the 4-wheel discs on the E cars.
