Best car buying experience yet!
I recently purchased a new Suburban at T-Town Chevrolet. It was hands down the best car buying experience I have ever had. From the minute I walked onto the lot I felt welcomed and comfortable. The salesman was very knowledgeable, extremely helpful and not pushy at all. I walked away that night feeling great about my purchase. If you are in the market for a new Chevy I highly recommend T-Town Chevrolet.
This truck has a jerk when changing gears sometimes.

Shoutout to Tiffany at Winchester Mitsubishi, she made everything easy before I even stepped foot in the dealership. Super knowledgeable, easy to talk to, and actually listens to what you need instead of just trying to push you in the door.

Best dealership in Kentucky and it's not even close. They are kind and interested in getting to know what is best for you. I never thought I'd say that about a car dealership, but these guys are second to none.

I had a great experience purchasing my used 2023 Tesla Y
I had a great experience purchasing my used 2023 Tesla Y from Lumin Fisker! I worked with Alexandria who was very helpful in selecting this vehicle and answering all my questions. She really wanted to make sure I got the right vehicle for me even if I had to go to another dealer. In the end, the Tesla was the perfect car at a perfect price! Pete even found that he could beat my banks financing rate and so I got the car at even a lower monthly payment amount! Way to go Lumin! They were really nice to work with (not pushy) and made the transaction a very pleasant purchase experience. I will be back when I need my next car!
