Technically, this: [link]
But I don't really count that one, as it was made in Photoshop with vector objects.
My first Illustrator vector was this (and the first I strived for realism): [link]
My last was technically this: [link]
However that was mostly made for selling as stock.
This is what I consider my last "true" (realistic) vector, which I made for fun: [link]
I've posted a couple since, but they were made before this one (just late posting them). Also the date I posted that one - April 7, 2009 - is the last time I made one.






Good Luck!
My first vector was made in...*gasp*...Microsoft Powerpoint. I actually got further than that, but the file corrupted, and that's all I had to go back on. I gave up because that program is not made for that sort of thing
My first vector in flash was this crappy looking Supra
The last car vector I finished was an AC Schnitzer BMW M Coupe.
Quite a difference there
I've currently got 2 car vectors left in my backlog, one of which has been painfully close to completion for over a year.
