Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Beautiful car mate.
If your looking for suggestions for mods which aren't going to put you out of pocket. Here are some I've done to my VE Calais
Mirrors (I have chrome but you can find silver ones)
Lip spoiler. Just adds some class.
Rims. If your not lowering it like me, just go 18's or 19's. 20's look funny not lowered.
Now..you can alsO change your door handles.
And you can change the exhaust so you can get quad tips (pretty cheap to Do - I just have an ssv exhaust on mine)
Then you can always do interior mods too like sound systems and headunit and lighting etc
jeez mate if it had a set of ss 18s it would be my car ,as for the rear bar mines the same depends on the angle your on as to how different it looks a quik boot debadge and ya set im thinking a big single chrome tip for exhaust just to be different , a bit old school , i also picked up a set of sv6 side skirts looks neat .
Looks nice Bro, Why not pick up some SSV head lights also? A set of SS rims would look good too, considering you are getting new tyres this would be the time to do it.
Check out my Omega for plenty more ideas
Don't worry about what appears to be discoloration.. If you look at all VEs etc it's the same... The paint reflects differently of plastic than it does off metal, so sometimes gives the appearance of a different shade etc...
Tasteful mods, well done mate.
