Ditto in NZ too, a number of Mk1 Uno 45 models arrived in 1989 with the 903cc pushrod motor - most seem to have been either badged 45-S (plush seats and carpet, 5-spd with 'short' 5th) or had 'Sting' decals (ordinary trim, 4-spd)
The plain-jane Mk1 45 in beige, blue, white, or red, with no headrests, no rear wiper, and 4-spd had been fitted with the 999cc FIRE since 1986! So for NZ it was the 'specials' that got the noisier, less-torquey engine with the old points ignition to go with your fancy seats, metallic paint, pinstripe, and sunroof - pretty funny really...
I have seen a Mk2 1991 45 3-dr once in NZ, which also had the 903cc engine - bizarre. Mk2 was slow to arrive in NZ and was outsold by used Jap imports, which cranked up about that time. I guess for the price of a new 1991 Uno you could have a 1988 Nissan Maxima with all the bells and whistles.
Anyway this is mere trivia
Lewey and Louie are right, a 999cc is always a FIRE.
