At a guess there would be plenty of crashed ones around for a $5k fun car just do the work yourself
I think this thread just comes down to what you like, I don't like the diamantes I think they are big slow and ugly all the ones I have driven have been like that my mate has owned a few and all of them I was able to beat with my 1800 NA DOHC TX3.. But they are great cruisers and really comfy on the open road which is what they were designed for. I don't like the preludes either they just didn't drive nicely and weren't all that fast for a 2.2L would rather go 1.6 or 1.8 vtec in a civic or integra. The integras you drove were they both DOHC vtec? There are plenty of versions of them some have SOHCs which are nowhere near as good.. I am a fan of hondas too have been in quite a few very fast ones, but the black tops are great engines and in a really good package from the factory as Paul has suggested. Unless you are good at fixing stuff I would stay away from WRX's and most other turbos in that range they would be fairly gone by this stage, but advantage is there is alot of parts around for them as everyone crashes them so you could keep one running.
This is an interesting discussion would be interesting to see what you end up getting
