Yeah, I know that... Maybe you've bought different tips to the standard ones?
From what I can see, Phase 1s had standard tips that are harder to clean. Phase 2 (Coupe included - all of them) have the chrome tips as standard, which look 'thicker' and are easier to clean.
P.S. I think silver is one of the best colours on a coupe... It'll age VERY well in silver in my opinion, compared to some colours. I'd love another one in silver for the other half!
