help finding a car
I'm new to this forum and BMWs I currently own a 2001 Honda Civic which I use to commute to work. I've been looking for a used BMW at cars.com and see that 540i is within my budget of $12,000, I like this car but a friend told me to stay away from the 8 cylinder and that I would be better off in a 325i, 328i. Honestly I like the horse power that the 540i has but it does require premium gas and there might be some reliability issues (???). Can someone recommend a reliable and dependable model and year, I will primarily be using this for commuting during the week and for me and my wife and two children on the weekends. Any advise will be much appreciated.
