i had a fastback myself a few years back and i like the stock style of the fastback, but if you have the means to do a silvia conversion i would definately opt for the coupe. one question though... which conversion would you go to: retain the s13 silvia theme or go for a newer s15 conversion. if you were planing to do a s15 conversion, the fastback is a much better car style-wise for a s15 front end. imo. good luck and sorry about the z. you wont be dissapointed with the 240.
