I insisted on a manual tranny wagon. Preferably white, preferably a 5 series. I looked for a year. I found only one manual 5 series wagon in all that time, and it was snapped up by an employee of the Range Rover dealership that took it in trade.
I ended up with a white 325 manual wagon with 100k miles on it. I like it, but it is half as fast as the 328 I gave my daughter, yet gets 3 mpg lower mileage. The poor mileage is because of the low speed rear end that they put in the 325 e46 wagon and convertible.
I passed over several beautiful manual tranny 528 and 530 sedans. Sometimes I think I should have snagged one of those instead. A 528 with a fold-down rear seat would hold about as much as my 325 wagon.
