Seagull is a good car, but it is ultra small.. The major achievement is a $300/kwh price for just the battery in China. Would be easy to pay for car just from V2G or V2H+solar value. Ultra small also means the highest efficiency, and range charged per hour.
There are a lot of cars that are model 3 "sized"/comparable. BYD seal is $30k in China ($2000 less), and more expensive than Tesla in Germany. It might be a better car to boot, but its not helpful comparing Tesla to Seagull prices.
