Yes, I've seen your top thread, and feel your 'hail' pain.
If you read that ID thread, you can input your VIN and your wife's VIN and get more information about your cars.
Someone has an OEM top which needs a rear window; you might consider making them an offer or explaining your budget. This is a forum for the 'money-tight', so don't feel like the lone stranger.
$500 for a 1.0L engine and transmission, or a bit less, considering he'll probably take a loss to get it out of there, isn't really a good deal, especially in view of the poor compression results, and your geographic region.
The compression tells me the engine IS ON THE WAY OUT.
You'll have to rebuild it before you put it in anything.
You could probably find a great engine/trans in a junkyard for half that.
Maybe because you are young, he's taking advantage of you.
Never believe ANYONE when they say an engine has 30K, 40K, 50K on it.
That's a common phrase people use which can
never be verified to cinch a deal.
Hopefully you'll realize that.
He could always say, "I THOUGHT it had 40K on it; maybe I was wrong."
Geeze.
Don't ever go back to that guy, and when he calls, tell him your wife won't let you buy it...yet.
You might think about what you could do with $500 in parts.
$500 for this

(DOHC with Turbo Tranny)
might be a good deal if it was in good running shape, but that guy isn't doing you any favors.
$500 for this

(DOHC engine COMPLETE -alternator/intakes/water pump/etc.etc. in PERFECT running shape and GT Tranny in tits condition)
from an Los Angeles area junkyard is the going rate...and our California prices are about double yours.
So don't think this is the ONLY deal in town.
A 3 cylinder should cost you a lot less.
Maybe the guy is using you to pay for his retirement.
If you are clean, hard-working, and have good attention to detail, you could easily rebuild the wife's 1.0L engine for less, using the parts recommended on GeoMetroForum.
That should include some fancy-schmansy head work by one of our Moderators.
(No, I don't get a kickback for referrals...)
Yes, it does require the 4 letter word (work) but for the greatest satisfaction, that would be the way to go.
Otherwise, you are just spending too much money on a boat anchor.
Take apart the wife's engine, replace it with new parts and you know EXACTLY how many miles are on the fresh rebuild.
Don't be scammed by someone who tells you 'Joe Blow' built this engine way back when.
You don't know how it was driven, when the oil was changed, etc.
Rebuild the engine yourself and use that Suprf1y head package.
You might not like the results, though.
The wife would kick your butt up and down the block in her car.
Kind of embarrassing; you do all the work and she gets all the glory.
Anyway, if both the cars are running, maybe you don't NEED the extra power plant...if money's tight.
The above advice is what I have learned from being a member here.
By closely following the various Do-It-Yourself threads, and NOT getting fancy with MY WAY, we have gradually gotten to the point where money is tight, but not too tight to mention.
Translation: our debt is decreasing.
You would do wise to enlist the help of members here which are competent and local to you.
Do not expect anything for free.
If you get some help, plan on paybacks, which reminds me: you will be posting updated pictures when?
Well, it's time to work on some alternators, so you think about what I wrote.
You haven't found the 'deal of a lifetime'.
Just stick with what you've got and fix it up.
