Hello and happy new year to all. I'm totally new to this and a little at sea. so can some one help me out?Spent the last month doing the look through all the BMW's for sale in the Big Smoke etc (auckland i think it's called, no offence to any Aucklander!). and have short listed about five of them mainly by price and k's, checked out turners auctions for prices etc so that side of it is ok but in searching the net have found it to be all overseas stuff and most are the larger engined BMW's 545 bmws etc. The one's I've found are imports 2001,2002 520's facelift model, 2000 523's and maybe a 528,or even 530 of the same year. the doubt i have is in which one, the small 2.2ltr motor and get good mileage but run the risk of having to push it hard to make it go were the 523 has a bit extra, 300cc and maybe better the same for the 528 but lose on the other end on the fuel econ. Or is my thought process all wrong. Can some one please help me out because if you own a 5 series you will have first hand knowledge and that is what I'm after any help with this will be appreciated and a BMW will have found a new owner. The next step is the tit avating up will begin all good spare part sites will be welcome. Have heard that the audio in some of them is not good any suggections on replacement units and costs.
