Excellent staff. There is a blond woman in service that swears a lot. This is not a good image for Colonial. I have heard her use the F word 4/5 times I have been in There is a blond woman in service that swears a lot. This is not a good image for Colonial. I have heard her use the F word 4/5 times I have been in there recently. She sits right were the keys are hanging. It is a real bummer as I heard her telling a tech that the customer should “go pound sand”. It kind of makes me think that there is not a customer first attitude there. However, Peter, the manager is very good and so are the other service intake people. More

Service agent was rude, unhelpful and lacked communication skills. When I bought my car, they told me they would have loaners if my car needed to be serviced. When I made my appointment for s communication skills. When I bought my car, they told me they would have loaners if my car needed to be serviced. When I made my appointment for service, they told me it was at least a month. Wait for a loaner car. I dropped my car off and had to call multiple times to try to get an update. By 2 o’clock in the afternoon, they still hadn’t looked at my car and were very rude to me with very little communication from them. I was then told by the service advisor that this was a lot for him to handle because he was having a really bad day. He also then explained that my car may be in the shop for 4 to 5 days. They never mentioned that when I made the appointment. And didn’t seem to really care that without a loaner car this really wouldn’t be possible. He then mocked me, put me on speakerphone and then offered that I would get a Uber to come pick up my car. More

Colonial Cadillac rolls out the red carpet whenever I bring my car in for routine service. There’s coffee, snacks, TV, and Wi-Fi if you want to wait, but I usually take advantage of the shuttle. If yo bring my car in for routine service. There’s coffee, snacks, TV, and Wi-Fi if you want to wait, but I usually take advantage of the shuttle. If you’re considering an EV, test-drive a Cadillac. Mine is more comfortable than my couch, yet with 515 horsepower, it’s quicker than many gas cars I’ve driven. It feels solid and smooth, recognizes speed limits, responds to voice commands, and offers hands-free driving on compatible roads. Regenerative braking is another feature I’ve come to appreciate. I worried about range before buying it. After a year of driving with roughly 320 miles of range, it hasn’t been an issue for me. I charge at home most of the time and use public chargers on longer trips, often while I’m shopping or doing something else. At my rates, charging a 100 kWh battery costs about $25 at home versus $50 at a public charger charging 50 cents per kWh. I’ve also had convenient, fast charging stops at Tesla stations. I’ve driven, bought, and leased luxury cars since 2001. Cadillac has become my favorite. It has the comfort I want, the performance I love, and technology that makes it feel like the jump from a flip phone to a smartphone. If you’re curious about EVs, take one for a drive and judge it for yourself. Bradley More
