They aren't dismantling it. As part of the new plan and ownership, the plant will continue to run. When smart production moves to China, the smartville plant will become MB's electric car factory. So instead of smarts they'll be pumping out more expensive cars with the MB star on them.
Pity gas/petrol engines are finished. Luckily I bought one of the last 453 Petrol Cabrios in April this year to come off the production line to the UK before it finished. So it will have to do me a long long while. Think Smart made a big mistake as Electric cars have big downsides like lack of range and being a lot more expensive. This is my fifth Smart Car since 2003, and I will not be buying another. If Smart think loyal customers will keep buying the brand with only electric cars available, then they may be in for a surprise.
