If you will read ADP's Annual Report you will find that the Automotive Division accounts for about 10% of total corporate business and about 8% of the profits. While the other divisions of ADP tout there TREMENDOUS growth the Automotive Division states "we retained a higher percentage of our existing customers this year then we did last year" translated - we did no lose as much business to competiters as did the previous year. A numbe of years ago ADP stated that they wanted a 20% growth rate out of each division. Automotive Division accomplished this for a few year by buying out competitors and related vendors. With Dealer numbers stagnant or declining it is difficult to grow especially with the little guys picking your pockets, (AutoMate/Adam/Autosoft/ETC) Look at the NADA survey from several month ago. ADP did not fare well.
ADP stock is very likely a pretty good investment but not because of the Automotive Division's performance. Most likely the Automotive Division is on the Sale Block at this time - but who would by it (maybe they could throw in some Pintos/Vegas/Colts) I would imagine Anti-Trust would keep R+R out of the picture. Maybe UCS (wouldn't that be fun), My non professional broker opinion ADP stock is a BUY. Use the money you can save by switching off their DMS system and invest it in their stock. Your just wasting your money on the over priced monthly fees anyway.
