Gentlemen, hope all is well. So...its the same old comparo between BMW and Mercedes. As much as i try to convince my dad to go for the 323i, it seems that he is leaning towards the Merc simply because his current e46 318i dissapoints him a lot, having to be in workshop always and such....and having been told that the e90 have some engine issue, he is even more turned off. Myself too actually, having the thought that a brand new car that cost above a quarter million, and actually need to top up engine oil every 8k to 10k? No kidding... Its actually kinda depressing, seriously. As much as i love the ride and the drive... Right here, i would really appreciate if you guys could point out the weaker side of the Merc, if any of you have any experience with it, compare to e90 and perhaps i could make my dad stick to BMW. Thanks guys..... Regards
