There’s a very fine line
Personally I wouldn’t buy a car that’s been messed with too much
Black wheels are something that makes me think cheap refurb
Coilovers are awful, usually ruin the ride and if not set up properly, which 99% aren’t, then handling is ruined too
Induction kit would also make me think the car has been ragged around its whole life, and carbon stick on bits look cheap
But, that’s just my opinion. It’s your pride and joy obviously, and it’s a beautiful looking car. Alfas are lovely.
If they are reversible mods you shouldn’t lose anything when it comes time to sell
