I did not actually drive the vehicle i was right there
I did not actually drive the vehicle i was right there but they sent carfax before i got there and saw it used to be a rental in Florida and not what i wanted. I loved that they did that before so i didn't waste my time even though i really wanted to drive it. I let them know i wasn't interested because of that and they were super understanding about it and said they would keep me informed if something else came in.
Nicest, best performing truck I've ever owned

I can't say enough about the good people and top-notch
I can't say enough about the good people and top-notch service at Inver Grove Toyota. These folks treat you with courtesy and leave no stone unturned when it comes to meeting the needs of each and every customer. The reliability and efficiency of the Toyota brand is mirrored by the wonderful staff at the best Car Dealership in the Metro. Special shout-out to Jeremiah Whittlef, who went out of his way to answer all of my questions and give me a complete demonstration of every facet of my car. Purchasing and maintaining a car can be stressful, but the expertise, diligence, and friendliness exhibited at Inver Grove Toyota allow customers to rest easy.

Jason was upfront, honest and straight to the point. Didn?t play any games. I was offered a fair value for my trade in (unlike other dealerships). I was able to get my trade in and drive away in a brand new vehicle all under 3 hours.
