Replying to: saratogalake (Sep 09, 2007 4:02 pm) I'm sorry if I offended any one earlier in my response to "Did I get a good deal?". But lets be clear. For GM, the options are where the profit is, and many of the options IMHO are horribly overpriced (e.g, the GM Nav) or ,again IMHO , dysfunctional (i.e., 20" wheels) and extremely costly over the life of the vehicle (i.e., the replacement cost for 20" tires). Please remember that for most of us we are spending after tax dollars so a 45K vehicle requires us to earn maybe 57K in a W2 statement. In other words, a 45K vehicle is going to cost us about 1K per week for 57 weeks to pay off. YMMV |

Currently looking to trade in my trusted low mileage 97 Sub for a newer 2007/08 design. I use it most for long distance highway vacation mileage, with very occassional (every couple years) pull the sailboat out for cleaning. Also use it on demand, as massive kid hauler. I was just at a dealership having a discussion about what options I needed, and the salesman was trying to convince me that the 4WD 'auto' setting, was the same as the Locking Differential. Now to me this absolutely makes no sense, unless it is done electronically via braking of the spinning rear wheel. How I thought this worked, was that the 'auto' setting basically ran in 2wd, unless it sensed it needed '4wd' and if so would shift the front wheels into 4wd-high gear by itself. (I'm personally not crazy about it doing that at what I understand can be at up to 55mph, and will probably control it myself in 2wd mode, but that is a separate topic.) I also thought the rear locking differential G80 option is the same differential Chevy has had for 10 years. Am I off base here and have an incorrect understanding ....or is the salesman all wet? |

Replying to: kiawah (Sep 10, 2007 10:47 am) ____________________________________________________________ That salesman needs a course in basic automotive applications. The locking differential has nothing to do with the 4x4 drive train system. The locking differential, formerly called PosiTraction works in 2 and 4 wheel drive and is active anytime you are driving. And that "auto" setting??? Who needs it. Most drivers report getting lower fuel economy when in that mode. Just drive in 2x4 until you need more traction then punch in the 4x4 button. No problem.

Replying to: blckislandguy (Sep 10, 2007 5:59 pm) Well I did start thinking about how they could electronically give you a locking differential. With all of the skid control technology and wheel sensors now adays...you could detect wheel slippage on a rear wheel, and put the brakes on that wheel, thereby forcing power transfer to the other rear wheel. Not outside the realm of possibilities, just didn't think GM did anything like that since they have called it the same thing (with the same option number G80) from my '97.
