Remember, you're only 21, you have the whole life ahead, don't rush into a decision that you might regret it later. Only buy what you can afford or stick to what you have. The depreciation will be serious on these cars, another factor to consider.
Your money, your life, your choice, but IMO, stick to the zed for now, clear your debts, buy a house / flat. The hype will be over in a a few days and you'll start thinking clearly again, ha ha.
