I had this similar experience with my  1970 VW Kombi, "The Little Engine That
Could"... We went thru torrential winter  storm from Los Angeles to San
Francisco via I-5 without any hitch . We drove across alot of 6 inch deep
floods across the freeway which stranded some cars.... I brought along my
emergency rain outfit/boots/tarp/flares/tools/spare parts which never  been
touched... I was impressed with its persistence thru the worst environment....
VW BUSES AND VANAGONS RULE!!!
