Is that a Birkin? It sure looks like it. They used to sell and service them at the garage in Vacaville, CA, where I used to get my BMW worked on.
Yes, it is a Birkiin. I got a lot a advice and even bought some parts from the folks in Vacaville. I was in San Jose at the time and it took me about 6 months to build it. It was one heck of a fun ride. Sold it a few years ago.
