The dealer I leased from (Grossman Chevrolet has been the best dealer I have ever dealt with. I have been to over 7 different dealers in my 14 years of car buying across 3 different states (formerly in the USAF).
The entire experience was great getting the truck and the visits after delivery have also been very positive.
Dealer . . Oh, they do SERVICE there too - I thought they only SOLD vehicles!
I'm hoping to need no warranty service, take care of all routine maintenance myself, and get reliability so good that I never have to worry about the 'big' stuff.
This theory worked on my '87 S-10 Blazer - it's never seen a dealership since I drove it off the lot new (major repair to date a new clutch and partial tranny rebuild due to a failed pilot bearing).
BUT . . if I do need warranty service, I'll be going to a dealer closer to home than where I bought. I found my perfect Av on GMBuypower in Colorado Springs (TEAM Chevy), but live in Greeley, CO - 150 miles or so north of there.
