Sellers aimed to satisfy

Immediately after telling the Saul what I was looking for, he led me straight to it. The pricing was very flexible and fair, and all the repairs or tweaks needed were met with friendly and time efficient service. I would recommend making Diamond Jim's your first stop when looking for a used vehicle. Thanks to Turk, Perry, Saul and Jared for their professionalism and courtesy in making certain my purchasing experience was the best it could possibly be!


terrible people that own the lot

Went there and got a car for 7k a nice clean BMW.... everything felt good when i first test drove it. nothing wrong with the car. after a couple days i started to hear noises. all my lights were coming on the dash board. and my car wasn't perfoming like it was suppose to. come to find out when i took it to my buddy's shop. the transmission and engine were terrible. and now my car is only worth 3k. Diamond jims sold me a car that had alot of major issues. I took it back asked them if they could take a look at it or possibly refund me for the money i payed on this car they said no. there sneaky, dis honest and terrible. Dont trust Diamond Jims!!!!!!


Excellent Experience

Purchased a car from the West Allis location. Joe and TJ made trading in my vehicle and upgrading to the perfect SUV a pleasant experience. My wish list was long and they worked hard to find me a vehicle that checked off all my boxes. Strongly suggest giving them a call if you are looking for a used car!


Great Experience, very professional!

Purchased my 2015 Ford Explorer from T.J. at their West Allis, WI. location. TJ was great; no hard sell, gave me information on vehicle promptly when asked, and gave me a trade-in concession bump on my vehicle and gave me a price reduction on the car I purchased. Their financing rates were excellent and they don't mark up the rate as well-known large dealerships often do. Took a test drive of the vehicle and TJ gave me my license prior to test driving. (Some dealerships hold your license until you finally say no multiple times). I will be back at Diamond Jim's when I'm looking for another car!


what a joke!

If you want to be told different things two days in a row by the same person then this is the place for you. One day they are willing to come pick you up and do everything in their power to sell you a vehicle. The next day they won't meet you at one of their locations to purchase that vehicle. When you have cash to pay for a Cadillac Escalade and they don't want your business.


Fantastic Experience

This is a great family business. Best used car buying experience I have ever had. It was 7 degrees the day I went. Both cars I looked at started immediately! Everyone was helpful and friendly. I got a great deal on an excellent car.


Buyers beware

This dealership buys junk and cleans them up very well and does not do proper inspections, buyers beware! I bought a nightmare from them, a true piece of crap! A $20,000 heap of junk I’ve stuck $5,000 in repairs in, in just 7 months


Diamond Jim’s /97th & Greenfield

Hi Everyone! I recently purchased my dream car, a 08 impala as from Diamond Jim’s on 97th & greenfield in West Allis. Going in I had a lot of anxiety’s about whether I’d get approval for a loan and secondly if I was fortunate enough to obtain said vehicle would the salesman/Dealership stand behind their product because even a brand new car or used can have issues but what’s important is what done to assist the customer in rectifying it. I did get the approval for the vehicle I wanted dearly and it was because of Diamond Jim’s (Tony) working hard and diligently. During the process he kept me informed about how things where going and relieved and any anxiety I had comin in yes, yes ,yes it was absolutely stress free and he delivered Thank you (Tony). After a couple weeks my vehicle needed some maintenance so I gave Diamond Jim’s a call, I left a message with the receptionist and she was very professional and concerned, she said she would deliver the message once he (Tony ) came in. Tony was very prompt in returning my called gave me a time and a date to bring the car in to be serviced, he made me feel confident that I was in good hands and that he or the dealership that he represented wasn’t going to leave me in limbo with any minor or expensive repairs being I just purchased the vehicle. I dropped the car off and at the end of the day I was contacted and informed my vehicle was ready and repaired. This Experience is something I hope and pray helps you or your loved ones when in search for a vehicle because there are a lot of dealers out there that sell you a car then leave you hanging when something goes wrong after theyhave gotten your buiseness/money or are rude and unprofessional. Diamond Jim’s made me feel not only me but my husband feel like a appreciated valued customer who in turn will be loyal customers. Again if you’re looking for car for yourself or anyone you want to have a positive experience in doing so, please stop in, please see for yourself at Diamond Jim’s in West allis,Wi 97th & greenfield and ask for (Tony) I promise u won’t be disappointed but you will feel appreciated and happy with whatever vehicle you purchase. Lastly thanks to all of the staff that I met at this location that I didn’t mention because all of you were great! Thanks again (Tony) for everything ��and Diamond Jim’s for standing by your word and vehicles Mrs and Mr Holloway��


Bought a 2011 Suburban

We purchased 2011 Suburban. My wife asked the salesman to do 2 things. 1. clean the inside and fix the bucked seat in second row. We trusted that those two simple request would get done. We picked up vehicle on Friday at around 6:30-7pm. When we got home, My wife found a dirty glove under drivers seat and all the cup holders were filthy and the seat we requested was not even touched. When we called, William Lopez, the sales person gave us the run around as did Clifton Lowder the person who did the car loan. They made us feel like we did something wrong.... My wife and I trusted them and they gave us their word. As of now, I would not recommend anyone making a purchase at Diamond Jim's.


Diamond Jim's

I traded in my car for a newer used car. I was impressed how friendly and helpful everyone was. Nick and Jared were so helpful, they made my process go smooth and effortlessly. They have a great selection of cars. I will defiantly go back and I will recommend Diamond Jim's to my friends and family.
