I had a 2 litre white 8v for 12 years, great car, finally sold it as got fed up with windscreen wipers.
Are you sure its Artic White, when I asked the Alfa dealer for some white touch up paint 11 years ago, he asked me the colour to which I replied white, he said it must have a name i.e. Artic etc, and sent me out to check the paint code (on the boot lid inside), I told him the code and he looked it up and then with a slightly red face agreed that the car was just "white". When clean it made all other white cars (including my new fiat 500) look off white. This really annoyed my cousin who had bought an old white Rolls Royce Silver Shadow in white to do weddings, he'd cleaned and polished it up and was bragging about it at my sisters wedding we went out side and it was parked next to my unwashed (for a month at least) 14 year old 155 and every one commented that the Rolls looked cream

Remember the 8v is the last proper 4 cylinder Alfa engine

is lighter over the front wheels and has more tuning potential than the 16v
