Right now thats an excellent deal. Most X5's are being bought for around 500-1500 off of MSRP...

you'll be the first on the board (to my knowledge) with 4000 off...

Maybe 9-10 months from now after demand has cooled off 4000 off would be just an O.K. deal...

With that being said, the E46 guys are right that 65 is still steep for just 260hp... If it were my money, I'd untick a few options and get the V8 for the same price. I just maxed one out, and then removed Active Steering & Ventilated Seats bringing it to 70,000 MSRP (also didn't put on the 20" wheels - but the 3.0si doesn't come with the 20" wheels). For $400 dollars more your getting an extra 100 hp, which makes quite a difference in a vehicle that heavy... Even with those options left on, it comes out just under 75 - and then bargain them down to 70.

My point is, the extra hp is worth it. If your parents really don't want the extra power thats fine, 4k off is a good deal - but bang for buck (and from a resale point of view) the 4.8 makes more sense...
