I hear you.
My car is a replica. I don't want a drag car either. I already have a T/A which was my old track car. My last V8 Replica was a bit too radical and I didn't really enjoy it. 300-315 HP in this one will be a fun ride and a bit more "tame" on the street. (and easier on the wallet at the gas station...)
Since I'm not really "into Fiero's" (ooops, can I even say that here....? ! ), I wasn't really concerned about the trunk / originality etc. (In fact, the small trunk even adds to the "effect" of the replica since it's just one more thing that does not resemble the Fiero.
After a quick sanding etc, it will look close to factory. (only about 7" less deep). It's just enough trunk for me. However, I don't really drive the car on a daily basis either. It's more of a "monthly car".
I'm not driving too fast, . . . I'm flying too low.
