How long do 2015 BMWs last for?

I'm looking to get either a 2, 3, or 5 series BMW at about 35-50k miles. At what mileage do their engines start having problems? And are they major/expensive problems? Please offer any recommendations you may have or better options for vehicles. My other option is a 2016 Ford Mustang (EcoBoost).

I would definitely go with a BMW over a mustang. BMW usually have a problem period somewhere around 90-100k. They will most likely need water pump, thermostat, cooling system, spark plugs, etc. With the mustang you'll probably be replacing a motor sooner or later, I know the newer mustangs have a big problem with head gaskets.

  • Why don't American cars last as long as Japanese cars? My family has owned a Ford Taurus and a Nissan Altima of similar model years. Both cars are still running, but the Taurus has very low mileage (it's a 1999 with only 85,000 miles) and the interior is in horrible condition and the plastics Ford put in have been known for breaking. None of this has happened with the Altima, even though it has more miles. Why?
  • How long will a chevy silverado last? Trading in my ford ranger to many problems and issues. Anyways I'm looking at some used silverados they all have over 10000 miles on them. Are they built like toyota tundra and tacoma where they will last forever. In the 90s my mom owned a chevy caviler and a chevy mini van both had the transmission blow quickly and they leaked oil all over the place. Are the trucks like this are they good trucks
  • How long, on average, does a 70's Ford ranger F150 transmission last? Thinking about getting this truck. Guy selling it has papers proving he's had work done for the transmission, but that was 15 years ago. Would I need to worry about the transmission being any good because of age? He's asking 2500, says it drives great. No problems under the hood, just cosmetology.
  • How long will my 2005 ford Mustang v6 last? I have 81500 miles on it now never replaced anything other then regular maintence such as oil change every 5k and did a tranny fluid change at 75k. I try to keep rpms under 2k I have overdrive on it! And i'm not a speed freak because of gas milegae! About twice a month I'll race someone at a red light! I have a cai, headers, exhaust! I'm thinking I can get around 150k put of it before a major repair any ideas on this?
