Hi, I'm bout to buy this 2001 318ci (1.9 litre) UK spec. I have been searching for 320ci (2.2 litres) for almost a year and didn't have any luck. So I kinda changing my mind now to buy a 318ci but I am still doubtful. I'm not getting 323ci or 325ci is simply they are out of my budget. Maybe some of the expert here can advice me. The reason I don't want 318ci is for the reason it's not a 6-cyclinder double vanos engine. However, recently I've heard that 2001 320ci (2.2 litres) have some problem in their engine, that's why in 2002, BMW go back to 2.0litres for their 320ci. And by comparison, 318ci have better fuel consumption since it's 4-cyclinder. Also the pick up of 318ci is better than 320ci even thou 320ci have better top speed. Is this all true? Can some one give me advice and pros and cons between 318ci (1.9litres) vs 320ci (2.0litres) vs 320ci (2.2litres)
