Near my place there is a country road with a long straight and a steep hill at the end, perfect for washing of speed. So its kind of a local benchmark. I tested a subaru up there WRX STI 206kw, top speed of 170kph. Holden berlina 5.7L v8 220kw top speed 190kph. Just installed my new 02 sensor today (pig of a job) and the car was feeling much better so on the way home I went past this spot. 170kph!! I thought that was excellent given that the car has 155kw and weighs the same as the holden (1600kg). So even by modern standards I still think these cars hold their own.
