Wow have we all forgotten Stop Light racing ! That;s why cars were modified! I own a 04 WRX Wagon and it can smoke almost every 50's 60's and 70's Muscle car made, just look at the quarter mile time's.
When you pull up to a light with a old muscle and some kid in a Evo or a new Mustang pulls up next to you, They will just laugh at you and blow your doors off . New cars are just faster and handle better now and the brakes are great.
That why old guys with money, will bring an old car into the 21st century and don't forget pride in your old car. My brother has a 69 Z28 with factory rear disk brakes which make it 1 of 200. It just sits in his garage because it's to rare to drive. I don't see the fun in owning something you can't drive.
