Steve_RI,
This is a tough call. I'd certainly agree with the need for a more economical commuter vehicle. And, I'd say going with a '92+ civic is a good idea since they are the first ones with airbags, albeit only on the driver's side for 1992.
Make sure you check for oil burning. Have someone drive behind you and check for blue puffs as you acutate the throttle. Check for oil on the plugs. Check for oil/coolant mixing. Most vehicles of this vintage will have some rust on the wheel wells, shouldn't be a big deal for a commuter car. As another poster said, demand receipts showing when the work was done...especially if they want a premium price. You can assume the vehicle will burn oil as most people aren't religious about their maintenance. Check the shocks and CVs. I've seen Honda alternators last until about 170k...But overall, working on these things is pretty easy and most of the general maintanance is relatively inexpensive.
We recetly bought my brother in law a 1992 Civic sedan with 98k on it for about $2500. It drinks oil and coolant, but it does return some fantastic mileage, he's gotten over 55mpg a few times.
My problem was that I had to buy him something pronto as we were driving him to and from work, so I believe we overpaid a bit on the vehicle. Of course, the week after, I see all kinds of things in the $2k price range.
So, although a Honda would be my first choice too, be patient...and don't be afraid to walk away from something for $3500 with 155k on it, that's just too much money, even if you can take it to 250k.
You can drive your Pathy to work for now, it's not the ideal, but it'll do while you're looking.
Make sure you check out other things. Some great values I see these days are later model Protege's and Corollas. You should be able to get something quite a few years newer than a Civic with one of those.
