91civic si vs. 91 crx si

I have the civic si now but a friend of mine has a crx for sale that is pretty nice. The question is what are the pluses minuses of the two?
I know one has a back seat and one doesn't, I want to know does one handle better than the other, does the weight differance matter? I am thinking of saying F@#$ it and use the civic si as a daliy and just go out and get a z32 300zxTT. Thanks for the input.

the 91 crx si would have rear discs and be a little lighter.

if racing, i'm sure the crx si would beat the civic si in a race

I really don't care about racing anybody that much, I do like power, handling, braking as much as the next guy. Style has something to do with it as well. The thing is I was about to buy a z32 and when I test drove it I felt like it would be needing springs before too long( the TT decked out is like 3500lbs !!) which is normal for this car, and was stamerd buy the price differance between what I could get for my si.
So I started thinking why not fix up my civic with the money I was going to use on the z32. For what I would pay to purchase the z32 I could probably get my civic( or new crx) the way I want it. Any input would be appreciated.

spend all the money on hookers never go wrong with that. no really id say do up teh 4g
