it depends what you want from your car.If you like the 7 you may be tempted by an E39..530 or 540,the 540 is available as a 6 speed manual.If you want a more connected drive then an e34,I guess the 540 six speed or an M5,but the 535 manual has its own attractions....perhaps a late 525 manual.The e39 would be available in a touring,but it seems most E34 tourings in the US(you dont say)are 525.
