Power:
I would say, go with the civic. If you want a fifth gen and if you have the room to do a motor swap, I'd say get a low mileage b-series or k-series(depending on budget). Both engine and trans. Do it yourself and make sure you do it right the first time or it will cost you money in the future. Don't buy a engine swapped car without knowing the person very well and known/watched him/her swap the engine.
If you can't do the swap yourself, but still want a civic, would do you think of newer gens? The EM1, EP3, and across seas civics do have more power than the normal LX/HX/CX/DX/EX have. They're so light that the power it does make, makes it a somewhat fast car(I want one myself
).
Looks:
If you want a fifth gen civic, I don't blame ya, I loved mine alot at first. I just didn't look enough, I jumped at it when I saw it. To many problems including a huge cancer tumor on the rear panel. I love that paintcolor so bad, but, after I got sick of the D, I searched again and found an EM1 all stock that I liked. I couldn't get a loan in time. He let me cruise for like an hour, where ever I wanted to go and whatever I wanted to do. So, I took it on the freeway, I loved the ride, it got up in speed so quick that I didn't have a better day driving a civic, I miss driving my aunt's 07 TL though.
All in all, if you want a Civic, look for a 99-00 or 02-03 Si, they're quick and they look sweet in my mind. If you don't like the interior and if it's possible, swap back to fifth gen interior, again, I'm sure that will work without heavy modification. As for interior, I've since people do some crazy stuff to the bodies of the EM1 to make it look like a fifth gen.
Sorry for the rant, but a fifth gen is nice, but without a swap, it will get boring without any bolt-ons(which doesn't do much to a D) or going N/A.
I know I'm Pro-Civic throughout this whole post, but come one, look at what website your on. I too hate the lights of the teg. The preludes are nice, but they don't look sporty/cool to me.
