528i vs 166, well depends on which is louder - ur head or ur heart.
looks - sorry but i have to give this to the 166. like bindablitz said, a black 166 with full kit and black tinted windows; u almost expect it to stop and have big burly men in pin-striped suits carrying guitar cases walk out. the car looks so MAFIA!
interior - also have to give this to the 166. very sporty yet classy interior. the 528 interior has the typical BMW look - functional but a bit spartan.
reliability - bit of a toss up here. i'd say BMW gets this one initially, but some friends have had probs with their 5-series, too. at any rate, watch out for that ZF automatic gearbox in the 166. not the strongest around. and the front lower arms go quite quickly too due to the added weight upfront.
build quality - BMW for sure. the italians need to spend more time making things fit right and less gawking at the pretty cars and pretty girls.
performance - outright performance the 166 should win, since its got more hp. might lose out just in pickup tho due to peakier nature of alfa V6 engines and lower torque down low. but in the high speeds, i doubt the 528i can touch the 166.
handling - stock for stock, the 528i is more planted in the corners and has more electronic doohickeys to make sure u stay out of trouble. 166 very front heavy and prone to understeer.
fun factor/driving experience - smiles per mile, i doubt the 528 comes close to the 166. WJ hit on the one thing that always puts a smile on an alfisti's face, and something that keeps us looking forward to the next time we get to drive our cars - the engine sound. just cant get enuff of it!
value for money - goes to 166. younger car for the same price. after the first 3-4yrs depreciation which is hefty, the normal alfa depreciation is about 10k/yr. about the same as a bimmer of a similar age. add that to the fact that ur getting a bimmer that's 4-5yrs older for the same price, the 166 gives good bang for the buck. bear in mind that u cant get a loan anymore for anything over 10-yrs old. so ur gonna have a hard time selling the bimmer later if u use it past its 10th bday.
verdict - if im letting the missus drive it, id get the 528i (unless she's a greasemonkey like me). less hassles, and u cant expect non-car enthusiasts to give the 166 the attention they require. if it wass for my personal consumption, i'd get the 166.
