Completely agree. I have an early 80's Mini that has been rebuild from the ground up, with totally reworked and properly aligned/set up suspension. It has been bored out to 1380cc and has about 120bhp (weighs about half a new mini), and is an incredible handling and very quick little car - endless fun. In a different league in terms of "nippyness" compared to the new cars dua to being genuinely small and light.
Still cant wait to get an R56 JCW though - new cars just make performance motoring so much easier and trouble free (touch wood) and certainly leagues more comfortable.
