And rely on it as a daily driver without adding repair costs to the cost of acquiring the vehicle. That could be mitigated with extensive service history but at that point in the vehicle's life you are looking at sensors, timing belts/chains, catalysts, turbos going out, and VW/Audi specifically had a problem with carbon buildup in emissions equipment. That's just the engine.

On the suspension side ball joints, various bushings, CV axles, etc. all are on their way out too.

Just keep in mind the cost of acquiring the vehicle isn't just what you pay the finance guy on a car that old.
