Hard to find
By Rand | on Saturday, September 11, 2021
Started internet researching cars we were interested in; BMW 5 series, and Mercedes C300. We took. Few local models out for a drive. One Friday evening my wife came across this Q50S with low mileage, one owner, and no accidents for sale at a local dealership. First thing she said is I found a car for YOU! I have never seen one before. We started researching the Infiniti Q50S and found it appeared to be a somewhat rare vehicle. That Saturday morning we went to the dealer and took the car out for a drive, well 3 hours later we were 90% sure we wanted it, but we decided to sleep on the decision. Sunday morning we went back for another drive. after a short drive we decided we had to have it. Cashed out on the car, and every since we have not regretted purchasing HER car. I have never regretted buying this car.… - 5.0
