What do you consider to make a car quick? Is it the 0-60 time if so what do you expect a quick car to make. What about the power to weight ratio, again what do you think this should be? Obviously a Lamborghini is quick (read stupidly fast instead of quick there) but thinking about real world cars that we are likely to own what feels slow and what feel quick to you? Does the baseline depend on what you currently drive? For me I think any car that does 0-60 in 8 seconds is suitably quick, anything slower than 9 or 10 seconds feels pretty slow.
