Thanks guys, I'm seriously considering doing this. The only problem, is my wife isn't a car nut like I am, and says she doesn't want to replace the 4runner. I can't blame her, as it's been down-right flawless. But, she hasn't been inside of a GX470 either. The only way I'd do this, is if the 4runner gets upgraded, because there are times when I'll need a big-boy businessman vehicle, which the GS430 serves quite well. A 325xi won't fit that bill, as it's too small.
Smooth, my approach is really more bang for the buck, and AWD. I know the GS is going to be a hassle at times this winter, even with the "snow" option activated. And I'm not going to put nobbies on it either, that just bugs me. I'd rather replace the car, then spend the next 6 months driving around with Mickey Thompsons on a Lexus.
When I was searching for a replacement vehicle for my wife's Honda Civic (ended up to be the Mazda), we were seriously considering a 3 series. I remember talking to a few people at gas stations and parking lots that had them, asking them how they liked theirs and if problems were an issue. Everyone said they loved theirs, had no major problems, and all were in the 100k+ mileage area. One guy had a 330xi with over 300k miles on it! And said it's the best car he's ever owned. They're basically the European Honda Civics, from what I can gather. Top Gear said the same thing. So if I found one with about 80k miles, had it checked out by a pro mechanic (there is a german shop two blocks from my house called Gearhead
http://www.gearhead-autorepair.com/ that everyone raves about in town), then I'd be ok with it. Considering the mileage that's going to be put on it, I'm not too worried about wear and tear from me. At this rate, I'll be changing the oil in the Lexus once a year!
RX: I don't have the time to do anything these days!

I've got about $900 worth of new parts for the Lexus sitting in my garage, that I ordered back in July (brakes, ball joints, plugs, pads, ball joints, fan belt) that I just can't find the time to get to. Our 3 year plan still exists, pending the economy will allow it. But, probably won't be NC anymore, thanks to Charlotte being wiped out by all of this. We're looking at Atlanta instead. But, if my company decides to go back to the east coast, which I'm 90% positive they will, then I'm the logical pick to run it. But, rumor has it, they'd like NYC or DC. NYC is a no-way in hell option. DC would be tough too, but it depends on the salary bump, which will have to increase dramatically for us to agree to it. For some reason, they're just fans of the southeast. Funny, considering everyone BUT us has a dedicated office in Atlanta. I was in Raleigh last Wednesday to inspect one of our assets downtown. I had dinner with some folks, and all I can say is the pieces to puzzle to execute the 3 year plan, are in play. The questions that remain is where, and the economy. Commercial Real Estate is being chatted up as the next shoe to drop. I don't believe the news reports at all, but I do think it'll take a hit, but not like what these "expert" idiots are saying everywhere. Too many lessons learned in the early 90's, too many tools put into place back then, for the industry to faulter like that again. Heck, we're two years into this recession, and it remains healthy, the only healthy sector left actually. Indications from the past few months on the bond markets certainly suggest a strong belief in the sector from investors, given the billions of dollars raised by the REITS via unsecured bond offerings, and coupons lower than mortgage rates. They put the offering out there, and investors snap it up faster than a Taco Bell drive-thru.
So...we'll see what happens, on all fronts. First thing, is getting the wife to check out a GX470 and get on board with this.
