Normally here, you wouldn't bother assigning the hash to "options" just to send in to Auto. You could write it as:

```ruby
auto = Auto.new({:color => 'black', :make => 'Volkswagen', :model => 'Golf', :year => 2012})
```

And ruby also allows:
```ruby
auto = Auto.new(:color => 'black', :make => 'Volkswagen', :model => 'Golf', :year => 2012)
```
Those will all get munged into a single hash variable. Finally, I really like this syntax better (the 1.9 hash syntax), but this is an aesthetic and team choice:

```ruby
auto = Auto.new( color: 'black', make: 'Volkswagen', model: 'Golf', year: 2012)
```
