We've entrusted our 2010 Mini Cooper and 2015 Mercedes E250 Bluetec (Diesel) to Belden's since shortly after each came out of warranty. Their work has always been superb, the cars still run like dreams, and we KNOW that Belden's charges a lot less than the dealership. Most importantly, they only do the work that is required: for example, if the car doesn't need a new filter, they don't put one in just because the manufacturer's inspection calls for it. Equally important to us: Belden's only uses manufacturer (or manufacturer supplier) parts. We could not be happier with the work that Belden's does on our two cars...and highly recommend them to everybody we know.
