Best advice is don't.
Most of these cars are used up and ready for scrapping, but if you're persistant you maybe can still find a nice one. If you do, you're lucky and in for a nice experience.
For the most part, "nice one" means one with records of lots of recent major service work, as these cars are ready for serious transmission work, serious HVAC system work, some harder-than-DIY engine work, and if a wagon, rear suspension work. It will need or will have recently needed a new ignition switch, and you will be stranded when it's your turn.
IMHO it's sad when an older car is no longer as good as it was when it was new. To me this means all new suspension rubber components and shock absorbers and tires suitable for a Mercedes ... which aren't found at WalMart, etc.
