I am a weekend commuter and cover around 700 miles a week. I have a number of old back injuries and comfort is a priority for me. I don't have a huge budget, and have been running a 2006 BMW 5 Series which has been great. I need to replace the car, my budget is around £10,000. Is it a case of same again, or is an older 7 Series an option, with about 50,000 miles on the clock?
