The problem as with anything old, is you need to drive a good one that feels like it did when it was coming off the line. Old knackers with tired suspension, brakes and engine are not going to do much for anyone, but get one that is right and it all makes sense. It was a car of it's day but limited in tech and better for it. Like a fine wine it needs to be savoured and you need to spend time understanding the thing. To compare it to a 320d is frankly preposterous. One is some car and one is a tightly built, limited run homologation special. There are many saloon cars that will hand a mid 70's Ferrari its arse, but get a good mid 70's Ferrari, the right one and who gives a stuff. Mechanical feel, engines built to race and set up sharp as a tack. Not all about going quick, the MX5 should teach people that.
