New guy to this group

Hey, everyone. Thank you for letting me join this forum. I have a 1999 Sienna I need to keep in good shape as it's our daily driver and I use it often for business. I've had two other Toyota vans, a 1984 bought new and driven about 230K, and a 1993 Previa that caught fire and burned up with 221K on it.
I like the Sienna best, and need to keep it for a few more years if at all possible.
Thanks!
RichardB
