I have the wife's 2003 Olds Bravada that she prefers to drive rather than the new Honda CRV, a EZGO golf cart, Kubota RTV900 all in the attached garage. In my shop I have my 2007 Chevy Silverado Z74, wife's 2013 CRV, my Lund 17' fishing boat, and my 2000 model 1500cc Goldwing SE along with my two ZTR mowers. None of these are getting much use now with winter coming on. We mostly use the Bravada for daily (or weekly) errands and everything else is parked. I try to use the other stuff enough to keep the batteries charged.
I am still trying to wear out the Bravada 4 WD that only has 100K on it with everything other than tires, batteries and water pump original. Just did the 100K service a couple months back, had all hoses, belts, brakes etc checked and all still in good shape.
