The new 5 wagon is obviously the solution, but I don't have that kind of money. That's why I'm looking at the E39.
I have driven an E60. I drove the inirial 225hp 2004 530i with SP, and was naturally quite impressed. The front end still has to grow on me I think, however it's a driver's car when properly equipped.
The car will be used for mostly errands and long distance trips. I'm not gonna be hauling things anymore. Renovation is done!
In my area, they are offering 2.9% financing on CPO 5-series (E39 or E60). I fugure, I can pick up a 2002 530i for example, with about 15K miles only for $25K US!
I could basically do a straight trade with the X5, and even get cash back.
