i might do another one too, this time im thinking ill go a bit retro modern, large and luxurious.
here are some of my thoughts regarding the entries so far:
YJ- love the design, very sharp and i LOVE the roofline, very sexy. However, i cant say the same for the interior. IMO It looks a bit cluttered and weird. I think some normal gauges will make it better, and the center stack, while attractive, doesnt seem very practical (with the wedge shape) IMO, perhaps you should make the top part (up until the vents) "wedgy", and curve it out when you get to the bottom. and add a CD slot while your at it I hope that helps.
Monte- also a fairly attractive design, but overall, IMO it looks a bit dated, which is fine if thats what you're going for, but i suggest looking to the STS/SRX for some inspiration for making it more modern. Also, you need to make your door handels smaller :AH-HA_wink:
Mr. Metal- i think what would benefit you the most would be ditching the whole retro thing. IMO the problem with your entries is that they dont really look cadillac with respect to caddys current lineup, they look too retro. Maybe if you combine some of the retro thing with caddys current design cues (like you did a bit with your XLR) it would be better.
