I'm speaking now, so listen up.
For several years now, General Motors has been making it intentionally difficult for women to purchase the full-size Chevrolet Tahoe and Suburban as well as the GMC Yukon and Isuzu Ascender. GM knows the prime targets for these vehicles are women, so they sell them in extremely difficult-to-understand trim levels hoping a woman isn't adept enough to do all the negotiating.
For instance, the Yukon comes in either 2WD, 4WD, Denali, XL 1500 2WD, XL 1500 4WD, Denali XL, XL 2500 4WD, and XL 2500 2WD trims. All except Denali are extremely stripped-down. From that, they have several equipment packages which are trim levels on any normal vehicle. So after choosing the model you want and negotiating its price, you then have to choose the package and negotiate its price. And the packages are even more difficult - "SLT package 1SD," for instance, invoices at $5233 on the Yukon, $4657 on the Yukon XL, and $4502 on the Yukon 4WD with Z71 suspension (which is a $640 option on its own yet is only sold with an equipment package such as 1SD or 1SC which is simply an offshoot of 1SD). Other packages like the "Safe and Secure Package" (whose price you also have to negotiate, of course) are even more trim specific - $1475 for the 2WD Yukon and XL, $1670 for the 4WD Yukon and XL, $655 for the 2WD Yukon and XL with SLT Package 1SD, and $850 for the 4WD Yukon and XL with SLT Package 1SD. Still more options and packages exist from there with still more qualifications. On the Tahoe it's even worse when required engine sizes are thrown into the mix. And all this is under the assumption that women are unable to hold their own in negotiating deals.
