Totally agree Dan! I've been in the business now 31 years, back when we started the first Online Automall on a BBS with a Tandy computer. 
Generally, we see these types of stats from dealers that report to us:
Increased lead volume 25 to 40%
Lead engagement over 75%
Appointment to Show over 80%
Closing ratios average 20%
Front end Profit increased by 25%
Back end Profit increased by 33%
Attached are some additional metrics.
There is a suite of products under GRAIL® DXP that will vary greatly on how they are used on dealer websites and social media.
GRAIL® DXP (Digital Experience Platform) combines pertinent shopping/buying website CTA elements (DriveItNow® inventory payment buttons, tru Shop-by-Payment® Facebook campaigns, tru Equity™ trade-In tool, tru Pre-Qualify™ instantly, and tru Express Checkout™)
Happy to discuss further offline.
