Welcome to this board ! I'm not too far in the Los Angles Forest if you need help with your VX. A few pointers to never forget.
I'm not sure which seat to use as all our kids are grown but I have heard of a lot of sales of VX's over needing a more kid friendly car. Just getting to the back seat can be a big challenge let alone trying it with child in hand. I have heard from some of the survivors of this they go through the back door and over the seat. Either way it's a challenge.
1. Always check your oil every time you put gas in. (I own 3 and have had a qt of oil burned in 100 miles 4x4ing)
2. Check the coolant level in the radiator (not the resevoir) often when engine is COLD !!
3. In the summer or higher temps watch the temp gauge CLOSE ! They can over heat in the blink of a eye a toast the engine. Every spring 3-4 will loose a engine do to over heating and running out of oil.
4. Don't trip on the ABS light.
5. Service the transmission often (30,000-50,000 miles and get a transmission cooler. The transmissions on these can be very temperamental on running temperatures. Transmissions might be the #1 VX killer.
