I installed the Hansshow Power Electric Liftgate for my Tesla Model 3 this weekend. The power frunk is also available at Tesla model 3 automatic frunk and trunk
You are able to get 10% off with coupon code M3RAI
I will install the trunk for $400 (+$50 for the sensor). Frunk for $300.
First 4 installs are $50 off.
In the future, I will also look into mobile service. Although, given the weather ahead, this may have to wait.
If you are interested or planning a self install and have some questions please feel free to pm me.
