Looking for an older volvo ... is this the one? what do you think?

I"m looking for a mechanically sound (cosmetics not an issue) for my
daughter to drive between Maryland and NY once a month or so.

I looked at a '90 GLT wagon yesterday. It has 186,000 miles on it. It
had been sitting for over a year. Long, sad story attached as to why.
Short version..The private owner's wife owned the car. She died when
her new SUV flipped 1 1/2 yrs ago.

The sunroof leaked (left open a little?), the headliner sags, it
smells musty, and a few unimportand pieces of trim are hanging off
here and there.The paint is bubbling here and there.. it just looks
neglected.

My thought is that while it was being used it was probably a nice car.
After just sitting.. this car got ugly.

He wants a lot.. I told his mother who showed me the car that I
didn't think it was worth 1/2 of the asking price. He wants 1,800
"because that's what the book is on it in good condition. I told his
mother (he was at a grieving group... really) I could offer him
$800.00 as it stands.

The car starts right up quiet as it should be, steering feels tight..
I can't drive it on the road. it has no plates. The
brakes/muffler/tires are good. The body is solid, but ugly.
Cosmetically it looks like who did it and ran... No service records,
but I get the impression that the car was reasonbly well cared for.

I don't know much about the GLT .Any suggestions about whether I
should try and purchase this one, or should I wait? Would it be worth
it for me to restore a car like this? I can do mufflers, brakes, minor
electrical repairs and the like.

Thanks for your time, and your thoughts in advance.
