Looked for a low mileage Acura TLX or TSX for six months
Looked for a low mileage Acura TLX or TSX for six months and I found this car near me. It was nicely detailed and looked well cared for from the posting on Cars dot com. The sales rep called me very soon after my initial query. The entire buying process took an effortless one hour and I was on my way with the beauty,

How easy it is to work with Johnson Auto Plaza.
Purchasing my new 2022 GMC Sierra was easy as buying something through the drive-thru. The salesperson, Chris Maneotis was awesome. He explained how my trade-in would go towards the purchase of the new truck and went over the financing and options. I would highly recommend anyone to work with Johnson Auto Plaza.
