The features on the vehicle are amazing, I really love the sporty look. And it is worth every penny, I honestly don’t think I would’ve found a better one for such a great price.

Highly recommend this car! We were looking to purchase either the Kia Stinger GT2, Genesis G70 or the Q50 Red Sport. Never got to drive a G70 due to limited stock, but got to test drive the Kia Stinger and compared to the Q50 it wasnt even close. The Q50 has much better rideability, more refined, quieter and faster. We are looking forward to enjoying this plush sleeper for many years.
