I just started getting into cars. I thought this was cool. I remember when
these came out. I never knew they were so fast.

Below is a link to the fasted AWD Cyclone from 1991. The chief
hits single digits in the 1/4 miles.

hellothere

this store called "auto toys" in downstate ny has two of them for sale...mint condition but still look like crap in my opinion but they are real quick...come to think about it i think im gonna go down there this week to testdrive one of them..always wanted to experience them firsthand

Scot

How could you call a syclone ugly? look at this pretty typhoon.....

I think they are pretty cool looking.....

Amazing that it took 14 years to get into the 9's with a Syclone..... Evo's are already there after less than 18 months....

Christople

EVO's have been made in Japan for years... I'm sure people over there got them to be that quick before us.

Nobody

There was a Syclone at the first track day I ever did. It was damn fast in the straights--but the car underseered like a pig and both the owner and an instructor found their way into the dirt at least twice. By the fourth session the motor went and the guy had to tow it home.

I was going to buy one of those way back when
