I've driven by Isringhausen and looked at some cars outside but the showroom was closed
It looks like a nice place. I ended up getting mine at Tom Woods over in Indy. They have a nice selection of Porsches to chose from. The initial buying experience was good but I haven't been back since Sept 03 because it is 2 hours away and I haven't needed any warranty work done. They seem competent and professional though and I will probably take it there for major work down the road.
