Hi Alex,
Kuro and Alezan was my first choice too, until I saw my GM with Alezan! Kuro is the bomb when it's really polished but its a b*tch to keep clean and therefore looking its best. In the end I got the GM with Alezan and I think it's the classiest, not to mention easy to keep looking clean and tidy. Just my opinion but I guess thats what you are looking for...
Regardless you'll love whatever colour you choose... the car is sooo sweet!
