I spotted this early today as well and it certainly caught my eye. Lovely preserved example but as Simon says it's the base model where the engine is concerned producing only 90 bhp without the fuel injection (the ie version had 122 bhp from memory).
CHT stood for Controlled High Turbulence and you have to hand it to Fiat for trying to make the mundane sound sexy!
I remember being very disappointed with the styling of the Croma when new ...after the traditional boxy shape for large Fiat saloons that had dominated that size of car in their range up to that point. The smooth curves and down tuned engine (in this example at least) combined with the continued departure from twin headlights (like the Regata, Argenta, S3 131) gave it an emasculated look in my eyes.
Now however, I do find myself attracted by the car despite not ever having driven one. I do very much cherish the idea of preserving original and good condition Fiats of any model and if I had the storage space this would be on my shopping list (for my Fiat museum that I will build one day....
).
Didn't Theo have a white one as well..? I wouldn't be surprised to see it turn up in North London to add to his eclectic collection of larger Italian cars.
