In terms of the MX-3 vs CRX I think what you are missing is the rear body stuff aerohead mentioned. Yes the MX-3 looks very sleek and streamlined but you are not looking at it against the "template". The CRX most likely fills the back area a little better and maybe even has a rear attachment point with that little spoiler on the back. The MX-3 most likely has detached flow starting at the B-pilar and all the "sleakness" of the back end means nothing. Makes one wonder how much an MX-3 could benefit from a pro-stock style spoiler and reaches "template".
