Notes:

* I have a heavy preference towards T1N Sprinters and want to stick to their platform. You can choose the vehicle if you'd like!

* I also have a heavy preference on the build layout. I'm trying to stick to one build design and refine it. It's served me well for 5+ years. I'd really love to collaborate on interior color schemes!

* Budget is flexible, quality is mandatory. The ideal first customer is on board with a used T1N and a very high quality build, for a happy-medium price point and a bitchin' ride.
