Hi
nowt wrong with the 3 cylinder 1 apart from sounds like a diesel, a bit slow -but once you get moving its OK on the motorway just keep it about 4k revs uphill - i use 1 everyday
on the motorway up to 80mph & get about 45 mpg on average but i do push it a bit,
the tappets are sometimes noisy when warm -check if it has had the gear linkage replaced a normal problem on the corsa C 2000 to 2006 not sure about the corsa b
make sure the engine lamp isn't on it can cost to have the fault diagnosed
good luck
