problem with dealer noit getting work done--byers remorse

OK, In Texas, the deal is not complete until the buyer drives off the lot. Just has to leave the premises, If he turns around and comes right back the deal is complete. If we have a customer that states after all the paperwork is done that they will come back at a later date to pick up the motorhome, we have them sign a "Storage Agreement". Once that Agreement is signed, the deal is complete. Doug
