If it was me I would spend the money on the car you have now. Not on looks, but on performance. Partly because I rather the look of the GC's to any of the newer models. Your not going to get a car thats any faster if you upgrade (in stock trim that is) and I'd rather spend the money making my car perform better. If your smart about how you do it 7k can make a reasonable difference to your car.
