How about a Volvo? Probably the most reliable of the european brands. You can pick up an S80 pretty cheaply, S60 holds its value a little more but you can still get an 06/07 with 20k miles for around $20,000. The XC70's also have come down in price now that the new model has arrived. Modern Volvos are really comfortable to drive, have good power, pretty good gas mileage, and have some of the best seats around.
