Firstmerxparts Reviews 

had to start court proceedings to get a refund on a part supplied as working and OEM - it wasn't . Took 6 months . Eventually when court date set they paid up

Extremely disappointing experience.
I purchased a bonnet for a Mercedes E-Class, but it wasn’t suitable so I returned it promptly and within the return period. Despite following all return instructions, I had to make four separate trips back and forth just to get my refund. The process was frustrating, time-wasting, and completely unprofessional. Communication was poor, and I was left chasing my own money for far too long. I wouldn’t recommend this business based on how they handled a simple return.

If you are reading this review I strongly recommend you do not buy from this company! In 11 years in the auto trade I’ve never had a worse experience. I purchased a complete Mercedes engine from First Merx Parts and what was delivered was disgraceful. To start the engine arrived coved in oil and heavily leaking, a quick glance could see may components damaged and missing. The engine harness had been cut in multiple places and parts stolen off it, additionally they refuse to provide a receipt. As a precaution given the state the engine arrived i had a cylinder leakage test conducted which showed major cylinder leakage on all cylinders meaning there was significant internal damage to the engine. After contacting first merx part, they agreed the engine was faulty and promised a replacement. After making me wait 3 months and denying a refund (against consumer law) I was forced to initiate a small claim court proceedings against the company and purchased a second engine from a more reputable parts supply. 6 month later I’m now waiting for the court to order a ccj to recoup my money. During this whole time first merx parts have not offered any sort of reasoning as to why they won’t refund me (having acknowledged the engine they supplied was faulty) leading me to believe they simply intend to steal my money. I encourage you to read reviews by other customers that seem to demonstrate this is a pattern of behaviour from this company. Furthermore there are plenty of other parts supplies that will provide a better quality of product and will actually follow consumer law. Save yourself the headache and use another supplier!

I purchased a rear light from them via 1stchoicespares (1stchoice.co.uk) on the 10th February 2025 and they sent me a tracking number at the close of day which showed the courier had picked up and I was told I would get the item the next day or 2 days Max. Fast forward to the 12th, I hadn’t received the package and the last update on the tracking was still the 10th. I contacted the courier company who had no information and asked me to contact First Merx to request an investigation. First Merx kept claiming the problem was in my area despite the fact that the tracking details and the courier’s customer service told me the package was in the collection depot near First Merx. Of course this company didn’t do anything about it and I was passed from pillar to post. I requested a refund and they kept telling me I would get my refund once they had received back their item from the courier. The guys were even rude and patronising on the phone. I eventually had to open a PayPal dispute which was escalated to a claim. This company refused to contact the courier they used and refused to process my refund. I’m glad I used PayPal to make payment instead of paying them directly. After 13 days of not receiving the item as well as the company not responding to my messages, PayPal closed the claim in my favour and refunded me today. FIRST MERX weren’t very helpful at all, had no intention of processing a refund and not sure they can be trusted.

Finally when I did go to them garage i did get very good door for reasonable price for my Mercedes 😊

You will get robbed. Thats how they work

Worst service ever do not use this con artist they took my money for 1 steering rack which ended going faulty after a month and nearly killed me by locking steering up so ask for a replacement which was told to send old one back then they would send a new one but garage only wanted to do the work once so I agreed with the sales man (con artist) who said pay do new one and they would refund both at the same time this was 6 months ago any time u phone the other department that sorts refunds out only works 1 hour a day more like once a year total joke do not buy from them plz

Bought a number of items.
One of which they could not provide saying I need to pay extra to get it removed?
I kindly declined.
To work with them I tried to take alternative item instead, but the prices were not doing justice.
E.g. I tried working with them to get alternative parts, but when I found an alternative they could not match the price.
Their policy is no refunds if parts are returned, in my case the part was not taken, I was asked to go upfront and collect next day. So I paid upfront. When they could not provide they refuse to give a refund, instead a credit note which is worthless to me.

Would never use them again, and I will be reporting to ombudsman service also.
Easy for them to take my money, but impossible to get it back.

More then 4 months ago we ordered parts from Firs Merx Parts. They sent us wrong, damaged and also overpriced parts. On the parts you can see that damages were old and someone was trying to fix them with glue. When we ask for refund, there were plenty of excuses like - Nobody in office today, We will call you back, We are waiting for our boss.... it took us around month to get some money back.

Also they never admit that they send wrong and damaged parts... they try blame DHL. Of course DHL have nothing better to do then glue on the way of delivering someone’s parts....

No one ever call us back.
We try to contact them good few times, and now it is more then 4 months that we can’t get our money back.
The worst service and attitude ever!
