Or it you have the money, if I could afford the 10-15K I would go for it, like my car for example, I've spent a stupid amount of money that will never be got back, why, because I can, love watching the race cars bashing through the gears, I would still be as slow as a old mole but it would be 10 x cool.
If you can afford it do it but always remember that a 5k job will cost 10k.
On a side note cosmetic body kits are like moisturising cream for men, ghey.
