Emerald,
So, I gather you're looking for a G50 but it doesn't seem to matter whether it's a coupe or targa. Your color requirements are going to be tough since you're basically down to silver, blue, and green. As you've pointed out by your links, blue seems to be the more common color floating around. What's your price range, if you don't mind my asking?
You may want to look at this one. It's got a bit of damage on the front valence but seems decent otherwise. Plus, no blue interior. I'd jump on it but I'm looking for something more 'turnkey'.
