Costco/usaa/etc car buying services
Wanted to see if anyone has gone through a membership service like USAA or Costco to get dealer quotes. They advertise as no haggle, low price services which keeps things easy. A co-worker said he got a good deal, though he admits not the best deal possible, through costco and it was painless.
Just wanted to see if people think this is the best place to go or if its better to just work through email and get dealers to bid against each other?
