[750hp]

The Arntz/Butler cars share the same incredibly strong chassis platform.
I really like the body shape.
Front suspension is now easily upgraded to the Fast Cars IFS.
Engine set-back just plain looks cool!
Fiberglass has proven to be very strong and durable over the years.

I had an Arntz before my Contemporary. In "period correct" styling, I'd say the Contemporary cars are generally built more towards the 60s appearance. In driving position, leg room, suspension dynamics and an overall feeling of solid construction, the Arntz(and therefore Butler) platform is my preference.
