Each of my vehicles has an inline 6, naturally aspirated with a timing chain, a solid configuration. I agree it's too bad these are not more common in modern vehicles.
1994 Land Cruiser (4.5L)
2000 M Roadster (3.2L)
2004 325Xi Wagon (2.5L)
2006 Jeep Wrangler (4.0L)
The land cruiser has 320k miles and we just returned from a 2500 mile road trip without any issues. At idle I can sit a cup of coffee on the valve cover and it won't spill. Very smooth....
You have some of the best of the best lined up there. I miss my six speed LJ all the time. Whilst in Afghanistan we had a ratty 90's land cruiser with the straight six. I'm not sure the oil had ever been changed or if any maintenance had been performed for that matter, but it didn't seem to make a difference to the LC. It's a shame BMW won't put their hottest engines in the wagons.
