Can't think of enough pics or words to go for each car on their own, so I'll do them in groups. The first four I just relabeled today.
Wheeljack is my favorite of the 84 cars. The racing deco and the Lancia alt mode are great, and the roof chest/hood feet design is probably my favorite transformation scheme for any car Transformer.
Hound is a great mold. The arms are a little stubby, but between the vehicle mode and the overall sculpt, he makes up for it. I think he's the first Transformer to feature an automorph, with the head and arms. He was one of the last cars I found. Mainly because I refused to buy him incomplete. The gas can and spare tire are a pain to find, never mind expensive lol. I think I paid less for the entire complete figure than I would have for those two parts.
Sideswipe was a real fixer-upper. He's still not perfect, but he's better than he was. I will probably replace him later. The Lambo alt mode is pretty good looking. One of he pegs on his hood is broken, and the chrome is worn.
Sunstreaker was a pain to track down in decent shape. My first one was trashed, the second one was bare bones, but in decent shape, still a few chips, but I'm happy with him, only had to replace the black bottom stickers, the rest were still in good shape.
