We are a husband and wife team having the pleasure of making the difficult decision on the designs. My husband likes your entries as do I but I am not as much a fan of the car concept design as he. I also like the colors in #67 over #68. I like the arc, and I get that it's very modern and cool looking but I'm thinking people may interpret it as more of a train than a limo. Font and spacing on the company name are 100% perfect.
#97. #98 & #99 are more identifiable as vehicles now, like the subtle spray in 99 but not sure about the blue underneath. Great job, all of these really stand out!
#97 & #67 REALLY have GREAT color appeal. Font is PERFECT and spacing is good. Still, the car has not yet done it for me. Maybe a smaller (sedan) type car? Or make it more easier to tell which is the front and back? I don't know. Something just not grabbing me.
