Hi mate,car must have tax for the rac to collect it and it could be a bit of a long old wait with them too but it's free after all!!the engine you want is often referred to as an x12xe also fitted in the older corsa from about 1998 onwards.be careful with these motors as although their a nice torquey engine and brill on fuel they suffer from headgasket probs,I've just changed the motor in one now and it's a really easy job on the c model,drop it all down in one,four bolts hold on the whole subframe!!! They're really popular cars and sell well,but check for any traces of Mayo whatsoever under the oilcap,there is a problem with the left side gasket where the water pump,timing chain sits.behind that is an oilway which is only seperated from the water pump by a poxy rubber gasket which deteriorates and causes oil/water mix.this is relativley harmless but your header tank gets seriously mayoed up and looks terrible.the gasket I believe is a piece of piss to do with the engine OUT so worth doing.totally agree with tabetha regarding the three cylinder 1.0,possibly the worst engine ever put in a vauxhall....mind you the 1.6 diesel of the 1980's was dreadful too!!!
