* = Toine van der Laan from mugello.nl wrote in early 2004:"I found the car in a barn, where it had been standing for 9 years. Someone hat restored it based on a 1971 Giulia 1300 TI: the original promiscua Polizia being rusted beyond repair, they used it's roof and rear hatch to build a "new one". When I rescued the car I had to put in new sills. We mounted  the dashboard of a 1965 Giulia 1600 TI and added the original Polizia details including the sirene. Finally we put in a new 2,0 liter engine, special vented brakes and a limited slip differential. Paint is metallic grey (grigio medio metallizzato).

And here's a comment by Tony Stevens of Alfastop:

Having owned one for 10 years I can confirm from my own experience that information on this model is extremely scarce. Going back a few years to the '50's, the Colli Giulietta Giardinetta was produced in a very limited production run (about 90 examples if my memory is correct) yet was officially listed as a Giulietta derivative in that reference is made to it in the Giulietta Parts Book - although I have never seen any publicity material apart from press photos. Colli then produced ambulance conversions of the Romeo van in the late 50's & early 60's which were sold by Alfa Romeo as official models.

The Giulia Giardinetta seems to have been the rarest Giulia derivative in that only about 100 or so examples were actually converted by Colli. The initial version was based on the chrome grilled Giulia TI & the Giulia 1300 & was probably aimed at the general public in that it was fully glazed & equippped with folding rear seats etc as a normal station wagon, as shown in Fusi. The rear tailgate was full length & extended as far as the rear bumper, the normal rear panel being part of the tailgate.  I saw an example for sale in Belgium in about '94 & I believe that the car is now in Switzerland. I have seen only one sales brochure for this model & that was a Colli publication. Unlike the earlier Giulietta model, no reference is made to the Giardinetta in the Giulia Parts Book. The majority of the Colli Giulia Giardinetta production was for the Police & Customs & were half car/half van in that the side panel behind the rear door was sheet steel with ventilation louvres. Later versions had a shorter tailgate which extended only so far as the usual saloon rear panel which was retained (for increased structural rigidity?).

The Colli conversions were carried out with factory approval/co- operation & used a complete new roof panel produced by Colli. Most were based on the 105.26 series Super, although some were fitted with a Solex downdraught carb as per the TI!  Whereas most italian small volume productions & conversions used production windscreens etc from other current makes or models, the Colli Giardinetta tailgate glass seems to be a special produced just for this model. The tailgate was incredibly heavy & seemed mismatched to the slender curved external hinges.  Alfa Romeo also offerred the Giardinetta to it's importers & dealers in many countries. Two RHD examples came into the UK in about '68 & were used as an express delivery van & by the technical manager of ARGB, one of these is believed to survive in a rather rough state awaiting restoration.  

There were also many unofficial conversions carried out by local carrozerie for Police forces who would buy a standard Super from their local & have it converted in the style of the Colli version.  To complicate matters even further, I have seen two examples of what appear to be genuine Colli conversions which were based on the Nuova Super......  The Giardinetta which I owned was produced in Jan '71, with hanging pedals & the shorter tailgate is now in Portugal & is likely to return to the road this year.
