"The red tip Hirschmann antenna we ordered is the real deal high quality part we hoped for and it arrived packaged well and soon after the order was placed by phone. A business run like that is hard to come by in a sea of mediocre parts slingers. Thanks for getting one of the final touches to us for our restoration project."
"Great customer service 10 stars!!! lots of had to fine classic parts for your 190SL to your 280SL. A long time client. I would recommend you stop by this website and take a stroll. You might find what youve been looking for.."
