Great product hunt @aaronleang!
Here are my thoughts for Tesla's flagship electric car, Roadster.
Pros:

• Of course, very ecofriendly, no emission of greenhouse gases.
• Very revolutionary design and challenges the traditional Detroit 3 (GM, Ford, & FCA) , German Big 3 (VW, Daimler, BMW) and Japan's Big 3 (Toyota, Nissan, Honda) to follow on the electrification of their flagship cars. Most importantly, these challenges the luxury automakers to follow the lead.
• This would be a hit especially to sport cars enthusiasts that are starting to turn down Internal Combustion Engine powered sports cars.
• Great speed and range which is a very great feat to achieve by a car being powered by electric.

Cons:

• This has been the issue, this electric car is very expensive, that's why there emerge a competitor which is based in China, Byton as far as I can remember, I always read the newsroom of company page and the articles found in autonews.com backed then when I was working as a Mechanical Design Engineer in Lear Corporation, which is a leading supplier of seating and e-systems in auto industry.
