I would like to sell the z3, have a few acceptable cars picked out the day I sell so I can almost immediately buy the replacement and I would like to have a few thousands dollar spread between my z3 and the replacement, at least $1000+. I can drive my van for aweek if I need to.
Catccc- where I live worrying about rust on cars is non existent. Not sure about the condition of your matrix.
If you have another car you can drive for a bit, I don't think it is a bad idea to sell the z3 and keep an eye out for the replacement. Maybe list the z3 on the high end with a firm price and see what happens? If you aren't in a rush, you might be able to wait for a buyer that is willing to give you top dollar for it.
@catccc in my area as long as it isn’t super rusted or have obvious major mechanical issues, you could probably get $2.5-3K easily.
My matrix... the rims are rusty. Lost the hubcaps over time and never replaced them, so it's not the sharpest looking thing. Other than that I think it is in good shape. It is manual transmission, though, that will probably be a little harder to sell.
I would also suggest getting seat belt extensions that extend above the top of the booster so that it's much easier to buckle in and you don't have to fiddle around looking for the seat belt.
Seat belt extenders are for people that are too large to fit in the regular belt, and not for child safety seats. Here is some language from a site that sells seat belt extenders:
"Seat belt extenders are only for use by those who otherwise cannot wear a seat belt as required by each user’s country, state, region and/or local municipality... Adults and children who can use the vehicle’s existing seat belt should not use an extender. Such unnecessary use,
including with child restraints, could result in serious personal injury or death... Extenders are
not for use with child restraints..." (emphasis mine)
Also, most, if not all, car seat manufacturers prohibit the use of seat belt extenders with safety seats, and most vehicles prohibit it as well. All CPSTs will you they are not safe.
Here's the workaround- leave the seat buckled and have your child slide in/out. Occasionally if they pull out slack too quickly when sliding in, they'll have to let it retract and start again. Or if they pull too much slack and lock the belt, you will have to let the belt completely retract and then rebuckle it. Slide in/out isn't that bad. On rare occasions when we have a 5th guest in our Matrix, I am the only one small enough to fit in the back middle seat between our two radians. But because there isn't much space, and the buckle is at a funny angle where it wants to sink behind the radian, it is nearly impossible to get the seat belt buckled once I am sitting. So I buckle it in advance, pull a lot of slack on the hip belt, slide it, tighten at the hip, and the move the slack to the shoulder portion and pull that over my head. It's a bit of commotion for an adult, but for a booster sized kid, it's probably fine.
