They sell DIY kits for some cars like beetle. There are more similar companies in UK. None in Ireland. Many owners are very very rich, some are using it to avoid London congestion charges by driving a cool EV. Prices around £40,000 excluding the car and the sky is the limit. As a DIY a beetle kit is relatively simple but expensive and very slow charging and limited range. They had a 3+ year waiting list.

Most of these conversions use relatively small batteries and try keep the weight around previous factory values. The old petrol tank when full is fairly weighty and the old engine is heavy. They tend to try improve the weight distribution to 50% front, 50% rear which gives the car better handling. Main issue is early conversions had no CCS so max 22kW charging rate which is impractical for long trips, combined with a small battery and old style non aerodynamic body means real world range is tiny with public charging mid trip impractical. That said newer conversions have CCS, 100kW+ charging rates and bigger batteries. Also Tesla motors tend to give the cars far more power than they had from factory. I would definitely be in the market for one of these when prices come down in 10/15 years. A used already converted car for say 25,000 euro a beetle or mini would be a great local car.
