Same here, since 1989.  They hear from me once, when I buy the vehicle and I
hear from them twice, when they tell me the loan is approved and 3 years
down the road to thank me for my business.  I wish that was the case with
the last car (Malibu) I bought, the dealer  heard from me too many times
during the warranty, needless to say, it is very unlikely they will hear
from me again!!
