One suggestion I have for them is to wash the inside of the windshield before the vehicle gets out into the sun - every visit I've needed a "sparkle re-do" when to get rid of the sun-smears when arriving home - a small price to pay IMO. In all LOVE this place and the great people who work there.

We brought my husband's car--just a few years old--to El Diamante in St. Charles for its first…read moredetailing after a family referral. When we got it back, the headliner was visibly damaged and now requires a full $900+ replacement. Our appointment was at 8 a.m. on July 22. From the start, the experience was unprofessional. We were told we could drop the car off the night before using a "key drop," which turned out to be an unsecured mailbox with no signage. They claimed it was safe and under surveillance. On the day of service, we had to repeatedly call for updates and didn't get the car back until nearly 6:30 p.m.--1.5 hours after closing. When we arrived, no one greeted us. We navigated to the back to pay, only to be told about a 4% card fee at checkout--something not previously disclosed. After paying, the staff walked off without providing aftercare instructions or our keys (they weren't in the car as claimed, but still in the shop). The pickup process felt rushed and uncomfortable. After a walk in the nearby park, we inspected the car more closely and noticed extensive damage to the headliner--particularly in areas where stains had been. Research confirmed this kind of fabric is delicate and can easily be damaged by aggressive scrubbing. I immediately texted them with photos and asked for a call. The manager, Nelly, later claimed the car "came in like that"--which is false. She insisted their staff would've reported any damage and said if they'd caused it, the entire headliner would be affected. That made no sense, as only stained areas would've been scrubbed. I suggested perhaps the damage was unintentional but asked them to take responsibility and help resolve it. Nelly refused and said they wouldn't accept blame for something they "didn't do." I followed up the next morning with more photos and again requested to speak with the owner, Alejandra. Nelly said it wouldn't make a difference and instead texted me their lawyer's number. No one even asked to inspect the damage. We took the car as few days later to a reputable interior repair shop in Naperville to get an idea of how much a fix would be. They confirmed the damage was clearly due to overscrubbing and could only be fixed by replacing the headliner. Even more concerning, I found reviews from others with similar experiences--one customer reported damage the same day as ours (a cracked windshield) and was also referred to their lawyer instead of being helped. Multiple reviews on Google and Yelp reflect a pattern of damage and zero accountability. El Diamante claims on their website: "Your vehicle is one of your most expensive possessions and should be treated with love and care." Our experience was the opposite. We paid $180 for the detail plus a $20 tip--and now face over $900 in repair costs, potentially leaving us $1,100+ out of pocket. We regret trusting this business and want to warn others so they don't go through what we did.

I had a lingering issue that my local mechanic (who I generally trust) quickly identified as a bad…read moretransfer case. Above 40mph, my car made a rumbling sound. The repair would cost about $2k. I wanted a second opinion so I brought my car out here, 45 mins from my apartment, but close to my parents. After about an hour or so, they gave me their opinions of what's going on. It was *similar* to what my mechanic said, but instead of the transfer case, they showed me a bolt from my differential that was rubbing and shaving metal shavings into the differential oil. There were several other things. They honestly let me know that it probably wouldn't be ready until Monday at the earliest (this was a Friday afternoon), which made since because this wasn't a quick job, and they needed to get some replacement parts on. Additionally they're only open til noon on Saturday, and not Sundays. I called them on Monday to get an update. Joe explained everything thoroughly to me on the phone. Letting me know how they were planning to resolve the various problems. They also changed their mind on 1 problem, and identified an issue that was masked by the rumbling sounds. This was my front left wheel bearing. They replaced my rear diff, serviced my front driveshaft, transfer case, rear driveshaft, full front left wheel bearing replacement. Indeed it took almost a week to complete, but the problem has been fixed and it's been about 2 weeks now. Also, they get the benefit of the doubt because some of the delay was caused by two of their partners giving bad parts. First, the brought a part for the front, not the rear. Second, another supplier brought in a used part that Joe said was not up to par in quality, so they didn't use it. Extremely pleased with the work, and the staffs knowledge and friendliness. I only really worked with Joe, who was a 10/10, I can only imagine the other managers are as well. Nice job!!!
