Two very good options Spring to mind immediately. 1) A 2012 or later Mercedes E550. This is the first year of the huge V8 turbo and reportedly does 0-60 in about 4.2 seconds but toddles around town like a kitten. 2) 2014 or later BMW 550. This was a mid-cycle refresh and the 550 got about 40 more ponies that really woke up the engine. I don't know which is faster but both are quite comfortable and are surprisingly competent even on drivers ed days. Both have a reputation for reliability. Yes, both are reliable. The Mercedes is particularly good. You can fit six footers in the back seats. It theyir knees hit if you move the driver's seat too far back. The Mercedes has a bit more room than the BMW.
