A friend of mine had this when I was a kid. I had the 1/36 Corgi version and the 1/43 Bburago example but this was out of bounds.
I can't remember who it was on here that I bought a MIB example from, together with a Y10, Volvo 740, Fiat Regata and Renault 4 but I still admire the 190 every day as its a brilliant piece.
Leave as is IMO.
I’ll leave it as it is, I partly bought it to save it from being ragged to bits by some petulant kids. I’ve had a good look at it and its not in that bad condition. Bargain at a quid anyway.
