"Just had my Mercedes GLE diamond cut alloys refurbished. Made them like brand new and a very fair price. I would recommend this company 100 percent. Thank you"
"ER Alloys have carried out 3 separate jobs for me on my Jags. The latest was to paint my wheels and brake calipers — always carry out excellent work at a fair price, and always a quick turnaround. I highly recommend them, wouldn't go to anyone else."
"Would highly recommend Leo. Really helpful arranging a date that worked for me, and had a really quick turn around for 4 diamond cut wheels. Was well priced and my wheels are looking like new again."
"Mercedes diamond cut alloys refurbished with this company and they were excellent — just as they left the factory. Highly recommended."
