Warning: Older cars are not for the lazy, scratch-arse-and-bounce-starter fellah... Maintenance and an observant eye is required to keep them running tops...
You can't wake up and drive off without casting an eye under the hood. It IS an old car, after all, parts can be fatigued. Anyway, the practices required to maintain an older car will only serve to save you worries, time and money even when practised on a new car.
(The concept of "ol' car=headache" is only proven true for blissfully ignorant fellahs who, it turns out, never checked the oil-level... or slackers who have problems with anything they own - or marry.)
My first car (120y, 210B model) was abused/molested by its previous owner - the carb top was held in place by wood-screws (it still worked). All the work I did on that car over the years might eventually have brought the total money spent on it up to $12,000. I bought her for much less. I started dexing in her and she ran like a healthy thief - until a couple of years driving on logger-destroyed roads under off-road conditions took her down. I have my claws in another one that has AC, a good engine, automatic tranny (bleh) but was the victim of a bad body job. The 1500cc A series that I used to race in the Datsun will be going into this one. It will cost me less than $3,000. (The owner wants to get rid of it.)
My Vauxhall cost me $2,000, and I use it for Solodex. Every couple of months, I use it as a daily driver just to keep the old girl happy. (Nothing kills a car faster than sitting down, doing nothing.)
A reliable Escort cost me under $4,000, but it needed some minor body work and I wanted the engine. It still sits in the garage glaring at me. Everything in its own time.
Good cars are out there. Good luck.
By the way, Lasers are nice to run (especially with a 1500cc) but when they start to rot...
Stay away from Mazdas. Like ghetto skanks, they look sweet... but maintenance is a beyotch.
Galants (the most comfortable car I ever drove) are great, but parts can be hard to find.
The bigger they are, the more surface area/old metal to clean and upkeep... Bluebirds, 280Cs, etc.
Just my 2 cents.
