You may consider Retiring the vehicle. To do this you go to the Vehicle page, click edit. Then scroll way down to the bottom to select Retire. Here is the description you see about Retire but really, if you contact us, we can bring it back for you.
A retired vehicle still appears on your profile page and in public statistics, but it won't show up in your garage, or your dashboard, or in your list of vehicles to fuel-up. Optionally, you can change the description to let others know why the vehicle was retired.
You can't bring a vehicle out of retirement, so please choose carefully.
What about changing garage order in general? I have autos and motorcycles in mixed order with no apparent order. Would like to clean this up. Any help? The order on my iPhone is at least alpha.
