My Premium 7 passenger with PKG#3, cargo cover, body side molding and a few other small items:
MSRP $37,970
Sales price $33,835
TAX $ 2,459
Doc Fee 85
DMV 465
State Tire fee 8.75
Total $36,852
Subaru Loyalty Certificate (500)
Out The Door Price $36,352
Sales price if you include the $500 Subaru Loyalty Certificate comes out to 12% off MSRP
I had previously posted I got 8.8% off. My math was off.
As for "stress free", I found the entire process totally stress free. I've been down this road multiple times with other vehicles, and I've always been able to get below invoice pricing unless it was for some "hot" vehicle. The key is to have a target price, email as many dealers as you can, and then play them off each other. In my case, I could have actually gotten a lower price from a dealer 3 hours away, but the tax rate at my local dealer was so much lower than the bottom line deal at the local dealer was better.
Don't let sales people intimidate or annoy you. They have a job to do and a sales manager who makes the final decision. At the end of the day, every dealer has a certain profit they must make or a sales target they have to hit. You will never know which it is. I made my offers a few days before New Years knowing dealers were trying to hit their yearly sales targets. End of the month or end of the quarter are also good times.
Finally, IMO the premium trims around here are likely easier to get deals on because the dealers all seemed to have a plethora of this trim level. They had far fewer higher level trim cars.
Good luck and happy hunting!
