This is going to sound like a real 'dad' answer, but I'd save your cash. Cosmetic upgrades to your current Ibiza will do little to improve it and could make your insurance more expensive (you MUST tell your insurance company). It might even devalue your car as second hand buyers rarely appreciate such modifications. A 2005 Ibiza will be less reliable and require more maintenance and will probably cost more to insure. Save your money, get a few years' driving experience and then look at buying something genuinely sporty, if that's what you want.
