Happy all around
 Given that I choose the lowest HP engine, I am impressed how  well it still performs, especially on the highway. I don't miss one Hp. I took it for a 1500 mile roadtrip and had the most delightful drive I have ever had. I have owned over 50 cars - so far the only section any other car performed better was in acceleration because I had cars with  big engines as well.
