Tucker Rival 3 stage vs normal 3 stage?

I just bought a car two weeks ago, and it was a similar thought process. It came down to two cars, and both would go from A to B, both would hold my kids comfortable and safely. One car cost $4,000 more than the other car, and had about 30,000 less miles on it plus being two years newer. It’s just a process of gathering information before buying something. The amount of of time and energy researching is directly in correlation with the cost compared to available funds to spend. We take about 5 seconds to decide to buy a $2 drink, but a $10,000 car may take 5 days to 5 months to decide. Likewise a WFP system for someone who’s never bought one may take anywhere from 3 days up to 3 months unless it’s somehow an urgent need. Thank you for the input!
