I just had my best car buying experience ever at Southlake Mitsubishi through Leighton, the fantastic and enthusiastic car salesman there! I was able to get a grand off the sticker price of my gently used Honda HR-V, and most importantly, no added mandatory markups, packages and warranties. Car buying has been extremely difficult since the pandemic, but I truly appreciated Leighton and the manager John’s honesty and integrity with the car buying process. Highly recommend this dealership for your next car!
