My van is my baby (I loves my dog [Wuff]). The biggest problem I have is that I can't find a maintenance manual for the body. She's at 100K miles, but I can't change the rear brakes because I can't adjust them out far enough to accommodate new shoes (they're pretty tricky for rear disc brakes). Other than that, she's great. I even figured out how to change the spark plugs without having to drop the main harness or the engine (not the easiest thing to do, but it's doable).
I have to give it to the 5-speed transmission. I love how she handles Wyoming and Colorado (the mountains are not a problem)...
The only improvement I can think of is in the AC dept. It's easy to forget about the button behind the gearshift. Who's bright idea was it to put the button there?
