I would not recommend purchasing from Orange Tuning. (orange-tuning.de or on eBay)
Great service until there is a problem then he disappears and stops replying to emails.
First issue was when he sent my item to the wrong address in a different country (old paypal address), even though I clearly stated in my paypal payment notes and separate emails what the correct address was.
Item finally arrived after multiple calls and emails to him to re route the package. I didn't have major issue with this as I understand these things can be overlooked from time to time.
Went to install item a couple of months later (as i was building up a bunch of suspension parts to install at once) and he had sent the wrong part (h&r cup kit with wrong front struts). This was unbelievable as we had discussed the right parts for my car in detail including specifically discussing that my vehicle has a 55mm front strut clamp (not 55mm). I even provided my chassis number which he said he checked and he would send the 55mm type.
He replies to first email saying he will rectify the issue, then promptly disappears off the face of the planet. No reply to well over 10 emails to firstname.lastname@example.org, multiple Skype calls/messages, website contact form, multiple phone calls off different numbers. This went on for a month and still no contact. I might add that all contact until the last email was very polite.
I've seen on different forums he is replying to other people and his eBay site is running with people leaving feedback etc so he is obviously still working and in the office.
I am now left paying a mechanic twice to install a part, a useless set of front shocks I can't sell and having to buy another set of correct shocks.
Absolutely deplorable service and I guess the volume of sales he does means he thinks he can just ignore the odd issue that seems too hard and it will go away.
