This is a good point. I've been mulling around with the idea of building an EV from the chassis of a car I've liked since the first time I set eyes on it. The Pontiac Fiero. Specifically the 86-88 GT.
It just looks like a wicked fun car and with the power of an EV driving it, then it probably is.
I don't have the space, money, or time, for a project car like that, but if I ever do, then that's definitely on a short list of possibilities. My only real concern is with insurance. I'll for sure be doing everything I can to bring the safety standards up to something modern (air bags, etc), and to reinforce the frame and make sure everything is copacetic, but I don't think insurance will care, they'll see an 80's era vehicle, that has been heavily modified...
I dunno. I'll make that call when I get there. The only real "new" features I care about are adaptive cruise, and Android auto/Apple car play... Everything else can be very bare bones... I have a very short list of things I care about beyond that, almost all of which were standard in some level of trim for the original car.
The vehicle has standard GM mounting points for the engine, same as any 3.4-3.8 V6 supercharged or NA engine from that era, so I'm sure some EV conversion kit will fit into the frame with little if any modifications needed.
Worth considering at least.
