A nice people and place to do business with them.
A nice people and place to do business with them. Mr. Cisneros and Mr. Velazquez went the extra mile for me. Highly recommend !
Am I the only one that has had the instrument panel
Am I the only one that has had the instrument panel completely fail? Mine did YEARS ago. So why is my reliability rating 5? The computer still works, I know how fast I'm going, the Miles remaining on the fuel economy is accurate, and it runs. Everyday. Replaced one hub and bearing, water pump, starter, ignition. A/C doesn't work, but I've got windows (which work if you know exactly where to push the button.) Oh, and the Engine light is always on, because the throttle body really needs a thorough cleaning or replacing. Motor and transmission have been crazy reliable for 20 years on truck bought new October '0 3. Nothing a few hundred dollars wouldn't fix. Though there are several of those, they don't keep me from getting from A to B.

Best truck, so good I’ve got second one
Bought truck brand new with 9 miles on it other than two water pumps and one fuel pump which were my fault for running on fuel. I haven’t had any complaints other than the guy on the dash peeled off minimal 53 runs great at 200,000 miles reprogrammed truck at 500 miles gets 20 to 22 miles a gallon down the highway as long as you’re on supreme runs great never left me stranded best truck I’ve ever owned I’m in search of another one similar same body style, but a three-quarter ton now but plan on keeping this is long as I can just purchased a brand new 5.3 to put in it when this one wears out it’ll keep going had minor issues with the dash gauges, light one out and a couple of gauges. No big deal, I also have an 03 Chevy Tahoe but it had all of the problems in the Insta rebel had panel replaced $600. No other issues. Great track Holly

Reliable As Can Be
Bought my 03' Sierra 1500 as a first vehicle. It was an extended cab with the 5.3 litre Vortec. After 245,000 miles I have had VERY FEW ISSUES, though I am the second owner and don't know of any issues prior to my purchase. During my time with it, I have only had to replace the 4X4 actuator ($500), headlight bulbs (typical), ball joints, and the rear U joint on the driveline. The motor has given me ZERO problems nor has the transmission. The interior has held up well with only a few small things like the coating on the dash peeling (has been very minimal). Only complaint is that the 5.3 litre is a little underpowered. I find that it frequently has to downshift when ascending in a canyon on a light gradient. However, this could be in part due to the age and milage on the motor. Overall I rate this vehicle as excellent!

I had no idea how stressful moving could be until I
I had no idea how stressful moving could be until I attempted it on my own. Thankfully, these movers saved the day. They arrived promptly, packed everything quickly, and ensured that nothing was damaged during the move. I really appreciated their attention to detail, especially with fragile items. The whole process was a lot less stressful with their help. I will definitely be using them again if I ever move!

Bought Toyota RAV4 from Matthew
Unfortunately, my car was totaled and I was able to find a very nice Toyota RAV4, that I’ve always wanted! Matthew was absolutely amazing. He was very welcoming and didn’t push any aspect of the deal on me whatsoever. He was extremely patient and very easy to work with. He made my buying experience extremely easy and fun which was a blessing because of all the stress I was feeling over my situation.
