Which X5 would you choose?
 

Both are 2011 35D, almost identical mileage and price.

Differences in options-

A: Comfort seats w/ massage & ventilation, upgraded sound, comfort access, heated steering.

B: Adaptive drive!, CPO, still has comfort seats but no massage/vent.

AD, absolutely.

As you will read the BMW ventilated seats are rather weaksauce. Heated wheel is a 'whatever' for me, and comfort access just a gimmick. (all IMO)

Sounds is nice to have, depends on your needs. I suppose one could upgrade speakers, but you cannot add AD.

GL

A

AD + Comfort seats all the way....

CPO,i do'nt mind about the rest.

Probably B.

Also, comfort access wasn't something I had to have, but it did come on our diesel and I love it.

I'm going with A because the upgraded sound is a must for me

If I was picking, it would be B for me, too:
CPO, AD, I don't care about massage seats or a heated wheel, (in Seattle?!), and 'comfort access', a solution to a question no one ever asked, imo.
GL, mD

Probably neither, I would keep looking.

AD gets great reviews. I am sure it works. But it is another thing to break and then fix, to me. If I needed the improved cornering capability then I would rethink my need for an X5.

Comfort seats are a must, I'll never go back. Massage and ventilation would be a negative, for reasons above.

CPO would be a must for me here, since that is the only BMW extended warranty available.

Upgraded stereo wouldn't matter to me, my stereos have all been better than my ears are.

Never thought comfort access would matter, then I got it in a package. I liked it, but could live without it if all else on the vehicle was what I wanted.

Heated steering wheel would be a must have. We all have our weaknesses.

comfort access is great. i could live without it but im glad I have it.

AD is a must, imo.

The answer is B Alex.
B plus some BSW speakers :)
