My husband and I purchased a $35k Jeep Wrangler from this dealership last night. Our experience with Ken, the salesman was great but Dexter, the finance guy was rude, condescending, argumentative and arrogant.
Lets start with the missing bolt/cap that bolted the hard top down which first, is a safety concern, not to mention that without it would cause the roof to leak but Dexter kept saying that it wasn't their problem if it wasn't there. He then said "Can't you use the one that is there for both side of the hard top"? What! He was also insinuating that we had taken it to try to get something out of it because he kept saying that he finds it hard to believe that someone missed that when inspecting it. Seriously, this piece literally cost $10 dollars, I was shocked! Luckily Ken went back, searched the Jeep and found it in the back compartment.
Next, the Jeep manual was missing so we asked for them to provide one. I mean who buys a $35k vehicle and doesn't get a manual? Well, Dexter said it wasn't his responsibility to get us a new one and we could probably buy one on Amazon. He was literally doing everything he could to piss us off and ruin this sale.
Lastly, I asked for a full tank of gas because the Jeep was on empty and I was told that because the vehicle was used, they would only put $20 worth of gas in it. At this point we were literally going to walk out but Ken has promised to get us a new manual at his own expense and he agreed to fill the Jeep up with gas even though 2 DIFFERENT PEOPLE told him not to. Seriously, 2 people told him not to do it? I have never in my life dealt with a dealership so cheap in my life. The vehicle in question only had 4100 miles on it, we didn't purchase a piece of junk.
I sincerely believe Dexter was treating us this way because we did our own financing through our credit union so he wasn't making any money off our purchase. The only reason we stayed and purchased the vehicle was because of Ken and the fact that it was such a good deal otherwise we would have gone ANYWHERE else but here!!!
We will NEVER buy another vehicle from this establishment again. They treat their customers poorly and quite frankly it is obvious that they do not care! Go ANYWHERE else and you will be treated like a respected customer but do not expect that here.. Beware of this dealership!
