Get a GPS or take a taxi because it's hard to find. Once you get there it's hard to park in the right spot. We had to move. They are in a boxed in area with limited parking. Other businesses rent there too and I'm sure they hate the fans taking all their parking. An employee keeps telling people to move their cars.
The first thing we saw was Horny Mike's bus outside. When you get close the paint is amazing. It glitters in the sun.
You walk in the shop and right away you are at the counter where they filmed many times. Beyond you find Danny's collection of cars. There are enough cars that you must adore at least one of them.
You can buy trinkets and such if you like. They don't take you in the working shop areas but the tour is self guided and free.
I loved being in the shop. I think you would love it too if you've seen the show.
