I placed an order with Owen back in May 2010 via Paypal.
I too was very hesitant to order from across the pond.... BUT, let me tell you I am extremely happy. It took about two weeks, because he makes everything to your specs. About two weeks after ordering, I received and email saying my order had shipped and the package arrived from DHL the following day, what a surprise.
Prior to ordering, I called him on the phone and that eased some of my concerns. I ordered the vinyl instead of the leather, with my total cost back then of about $440 (307.75 BPS) with new foams, headrests, clips and shipping. I'm putting those in my Spit and will order another set in leather for the gt6. As for the quality of the seats, I can only compare them to the OEM seats that they replaced, and they are superior to those. I've never seen the VB seats, so I cannot compare them.
I tried to find the seats locally, but the price difference was just too great to justify. Based on this one transaction I had with him, I will order again, and would recommend him to others. But if you have 30 minutes (he does like to talk), call him, it will make you feel better.
