That will give you them all in descending price order so the first one
will be the most expensive. You could have called it cars rather than
car_price to indicate that it is an array (or similar) of Cars. If
you want them in price increasing you can say
cars = UsedCar.find(:all, :order => :price)
or to get just the cheapest
cheapest_car = UsedCar.find(:all, :order => :price).first

puts car_price[0] would have done the same thing.

If you want to see the individual fields then you need
cheapest_car.make and so on.
Why are you doing it in db:seed by the way?
Have a look at the Rails Guides at http://guides.rubyonrails.org/.
They are very useful. If you are following any tutorials make sure
they are for Rails 2.3 assuming that is what you are using.
