My wife has developed a nasty neck condition and now feels every road bump. This is compounded by my BMW X5 Sport's 20-inch wheels etc. We regrettably must change vehicle. We love the high vantage of the SUV and the high spec. We were looking forward to retirement in 12 months and enjoying some longer trips - perhaps Europe, and also the likely addition of a medium-sized dog. We would love to retain the height of the X5 but the 'sway' may well compromise us. I currently drive 20,000 miles a year and would prefer reasonable performance. Your suggestions would be much appreciated. Budget is up to £40,000, secondhand is ok.
