Sometimes it is worth it. I spent 2 days to buy a truck. I flew to another state and drove it home. It mostly went according to plan except the leaky power steering hose that I spotted the first minute I looked at it - and then spent the next 5 hours waiting for them to fix it. I wish I could trade more weekends for $5,000.

agreed completely, the point was to explain how to get the lowest price out of a car dealer, not necessarily to maximize value.

some folks prioritize the former or feel like they have time to burn
