Hi!
The Monaco series were a "concesionaire version" made from regular GTV6 2.5.
They are not official Alfa variants os special series.
They were made by adding a tiny vynil stripe thru the sides with "MONACO" lettering. A pair of MONACO stickers were added in the trunk door (left side) and to the front panel, over the headlights (left side too).
Engines and gearboxes were stock 2.5.... so this car had a 75 engine swap at some point in its life... (a check to the engine number will throw light...)
Interior were all in leather, incliding door panels and their tops and the gear knob.
A Blaupunkt New York autorario with separate power amplifier/equalizer were fitted too.
I've seen one of these in Portugal, french reg. Red with light grey stripe. Interior was fantastic, nicely done. Engine was 2.5. Stock Campagnolo wheels.
