We are leaving on Tuesday for a drive from WI to TN for a school competition for DS11. My mom has generously offered to rent us a vehicle for the drive instead of 2003 Taurus. I have arthritis in both knees and feet. We are looking for something very roomy and comfortable, and easy to drive. I am looking at Budget Car rentals and I think we are going to go with either a minivan or a premium car. They would be the same price. A luxury car is far more expensive, so I'm not considering that. The minivan would be either a Toyota Sienna or a Nissan Quest. The premium car would be either a Toyota Avalon or a Buick Lucerne. Which style vehicle would you choose and which model would you request? The clock is ticking and I can't make a decision! Please give me your opinion. Thank you in advance!!
