AK is oh-so correct on the setups.
Many dealers make the assumption that the SPS/SPG data should be 100% accurate from the get-go.
You've got necessary tweaks where your shop deviates from the standard. ADP uses motors or a warranty plus percent for your prices.
If you don't verify the pricing, the writers will tell you when it errors on the high side, and the techs will tell you when it errors on the low side.

Can't speak for the RR guides, but the ADP guides have some nice features such as related/supplemental repair awareness and a nice windows navigation with web2006. Also integrates incredibly well with tech terminals.
