A syncro vanagon was tailor-made for your needs. There is nothing else out there.
Right now on
www.thesamba.com, page 2 of the vanagon classifieds, there is a 1986 syncro vanagon (not a camper, not a pop-top) with a Suby V6 engine with 2000 miles. I think those engines are over 200 HP. And it's located in Renton, WA. I'd drive up to take a look on Saturday. He wants $17,500, and it might be worth it.
