Find a comfortable car of the upper middle class.

Hello friends, I’m looking for an upper-middle class car for a maximum of 6000 Euros. I find the BMW 5 Series E39 very comfortable. The car should not have cracked the 185,000 km depending on reliability. It should make the 200 km/h. Nice would be automatic. It should also have some extras at least servo, air conditioning, electric window lifter, seat heating etc. The car what I’m looking for should be reliable, so I don’t have to pay stupidly and stupidly to keep the car in service (clearly quite oh I’m a male and 20 years old. The cucumber I want to buy should be a gasoline or one with LPG. The consumption should now be as tight as possible the BMW 525i has a great consumption despite automatic. So such a 540 or so it does not come into question it should be common engines. They are affordable. Through the TÜV it should also make best without big theater. What are your suggestions which I definitely want this comfortable feeling like in the BMW 5 Series. I like BMW 5 Series and Audi A6. Also the Jaguar X-type. Thanks in advance
