Another Hertz build?
Sub'd.
You should tackle the build yourself dude. Take some vacation time and just do it lol. It's fun, and you will learn a lot about your car with it all apart, especially if you have never taken it apart before. Also, just a personal thing, but I like knowing exactly every little thing that has been done to the car, which wire goes where and what it does, etc.
It makes troubleshooting 1000x easier. If you get it done by a shop, then if anything ever goes wrong, or you want to change something out, you are kind of tied to that shop.
Looking forward to seeing this progress!
