My family loves this Vanagon. We go camping all over the west coast and it suits all our needs. We have almost 200,000 miles on her, and the kids are getting older so we may need to get another vehicle soon but we'll miss her. Except for the time the alternator failed when we were in Yosemite, it hasn't left us stranded! My hubby does all the work on it so it stays in good shape!
My VW Vanagon had to have the cylinder heads replaced and the water pump too. The cylinder heads were pitted and leaking coolant, very expensive repair! Other than those problems it's been reliable and it offers a unique driving experience!
