The cost of a mini Cooper varies depending on what features the buyer wants. The starting price is usually about $19,950.
A decent trumpet on eBay can cost $100-$200 dollars. But when you go to a store to buy it, it can cost up to $1000 dollars, but it's usually around $500. My advice would be to rent it out until you've paid for it.
