absolutely. that's what in my family we have experienced with my 1.0 arosa (http://forums.clublupo.co.uk/index.php?showtopic=21812). it was bought in 1997 and is just over 100.000km now. it's not only about the mileage, but the "education" you give the car. for the first 4 years my mother drove it and when i inherited it was still sleepy. when my father drives it nowadays he totally feels new rage in the car. i always drive it between 3500 and 5000rpm in 2nd to 4th and to 6000 in 5th, the car is just used to go in that range, and therefore "asks" you to rev up since the beginning. truth is you can almost stall it in a lower range lol but the 1.0 can be very angry some times, especially if before thinking in putting a 1.4 16v you change the wheels, rims, brakes and suspension and drive fast through any corner at relatively constant speeds. that means flooring it (which is not much of an acceleration), but then keeping the speed in reasonable limits so you don't have to brake much. if you do, you'll need more acceleration at the exit of a corner than what this engine can provide.
