ok i for one and not a huge fan of lambos esp the murcielago. think its huge, slow and just a fat pig. the gallardo is ok but would have to be TT and the superlegerra edition.
the c5-c6 Z is one of my favorite cars eps the TT ones. 
the GT is sick as hell. love how low and small they are. add 2 snails and some nice wheels and u are ballin.
still not feeling the mustangs. sorry but i love the 03-04 cobras, not so much the new styles.
