Test drove the 2004 Thunderbird.
Test drove the 2004 Thunderbird. I said I was interested and would pay $14,500 for the car. They said there was a transmission problem with the car and could not negotiate until that was resolved. At the time the car was priced at $15,107. I have sent emails still showing my interest but have not received additional information on the transmission status as of this. I am interested and awaiting contact from Brad. Thank you, Tom Hatcher
Comfortable
Bought this truck used,I love the comfort. I used to have a ranger.I can fit my plywood in the bed and close it.It is a long bed.My 12 foot jon boat fits good,.better than the ranger and more comfortable

Cherif is amazing he's still helping me find an affordable vehicle. The vehicle I was to test drive was in an accident prior to my appointment. I'm a 63 yr old woman on a tight budget Cherif understands my needs and has been trying to find something for me, He is in touch with me daily, He has proven loyalty by his continued research of a car that is $4000 All my budget allows.For a salesman to work hard for me knowing I can only afford a $4000 car Is A Great Person .
Best truck I’ve ever had but needed A 3/4 ton
I hate to get rid of this truck I just don’t need 2 trucks. I would like to keep this truck because of al the work I Have done to it trying to keep it in good shape

waiting for approval from a company, they say I am approved but until in my name they want give me the money, so we are still working on it together, so until that issued is worked out I can't take the car home
So far so good
The truck runs great. preformed exactly how I need it to. Has everything I wanted except wireless/Bluetooth an back up camera. But all that can be installed later.

Good truck if you do the right things
The best thing about this truck is the fuel economy. Bought brand new in 2012 and when the truck hit 35000KM the fuel economy improved. I had heard about that before but didn't believe it. Beware, these trucks are known for transmission shutter and shifting problems like every GM product ever. Do not flush the transmission ever. Pull the pan and replace the oil three times every 40 of 50 KM. It costs a bit but the tranny will shift much better and last. The door handles are garbage. They cost 25 bucks on Amazon. Changed two now. Changed washer fluid sensor. Front breaks and rotors are cheap. Replace with high end aftermarket when they go...and they will. Over 200 Km on this vehicle now. Motor is strong and the truck is still holding up well. I would give it a 5 if GM would get their transmission issues fixed one day. A little higher quality front end parts would put them over the top. Good ride, roomy and comfortable.

My experience at Cars R Us was good.
My experience at Cars R Us was good. Marquez helped me out and he was cool to work with. Purchasing the truck went smoothly and negotiation went better than I thought it could. I wish I would have taken a longer test drive, as I found a few things about the truck after purchasing. But the men and woman at Cars R Us seemed like great people. Id recommended checking them out if you’re on the market for a nice used vehicle.

Everyone at Shifferly Automotive was incredibly friendly.
Everyone at Shifferly Automotive was incredibly friendly. I was greeted immediately when I walked in the door. I told them I saw their Subaru Crosstrek on cars.com. He offered me a test drive, and handed me the keys. The car was in awesome shape, and the price was right in my budget. I think I met the whole Shifferly family while I was there. They made it such a pleasant experience.

Looked all over the country and ended up here.
If you know what you want,and have the means this is the place. The Ken and Brian combo is the Best. If you want to haggle about price this is not the place. Prices are set to go against Nationwide market. If you do your research and they have the Vehicle, you're looking for this is the place. In my humble opinion.
