It was time to turn in my leased car & get a new one.
It was time to turn in my leased car & get a new one. It was quick and easy. Lots of upgrades in 3 years on the Equinox. Everyone was nice & helpful at Bocker's.
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

I purposely waited a couple of months before writing this
I purposely waited a couple of months before writing this review because I wanted to see what kind of follow up Rainbow did and I wanted to go through the first service of the truck with their service department. I purchased the Sierra 1500 truck with the small diesel engine in April. It has been a fantastic truck so far and I am getting over 30 mpg on the Causeway. First, it was a pleasure dealing with the salesperson, Rocky Comeaux. She was not pushy, she listened and she answered questions. There were two questions that she did not know the answer to - and instead of making up a response, she asked someone in her department. Having been in sales at one time for 8 years, this was refreshing that a salesperson did not try to "look good" in front of the customer and not look like she did not know what she was doing and made sure my questions were answered correctly. Rocky has followed up with me several times since the purchase to make sure that I was satisfied with my purchase. Second, I traded in a 2004 Dodge Ram truck with over 360,000 miles with the original motor and transmission. I take care of my vehicles, and longevity of the truck was important to me. As such, the long term warranty options were of interest. Rainbow explained them, and they treated me fair on my trade in. Third, paying for the vehicle was easy and picking it up was seamless. Fourth, I recently brought the truck in for the first oil change and service. The service department was booked for over a week but getting the appointment was easy on the app and I picked up the truck later that day at my convenience. The only hiccup on the service was that the DEF was not refilled. When I brought this to the service department's attention, they immediately apologized and filled it up asap. The service department was very easy to deal with and very friendly. I would highly recommend this dealership. This is my second vehicle I have purchased from them as we have a 2013 GMC Suburban still going strong.

Test drove the 2004 Thunderbird.
Test drove the 2004 Thunderbird. I said I was interested and would pay $14,500 for the car. They said there was a transmission problem with the car and could not negotiate until that was resolved. At the time the car was priced at $15,107. I have sent emails still showing my interest but have not received additional information on the transmission status as of this. I am interested and awaiting contact from Brad. Thank you, Tom Hatcher

As someone who had just immigrated from Korea, I had to
As someone who had just immigrated from Korea, I had to purchase a used car due to budget constraints. While I would have loved to buy a BMW, I ended up purchasing a Hyundai Santa Fe that BMW had taken in as a trade-in. The dealer I worked with, Gennaro, was exceptionally kind and responsible—so much so that he genuinely influenced my perception of BMW as a brand. One of the main reasons I chose this vehicle over cars from general used-car dealers was the trust I had in BMW’s basic inspection and standards. However, the way Gennaro handled everything afterward gave me even greater confidence that I had made the right decision. Having just arrived in the U.S., everything felt unfamiliar and overwhelming at times, but this experience reminded me that there are truly good people here. Honestly, when the time comes for me to change cars in the future, I sincerely hope to return to BMW and purchase a new car from Gennaro. I would even say that owning a BMW through him has become one of my mid- to long-term goals for my life as an immigrant over the next five years.
