I'm 5'11". It seems that the seat will not go low enough for me to feel comfortable. It's a small car. I feel like I have more room in my Z. There is a back seat, but it's almost useless unless you have the front seats moved up cramping the front passengers. The back seat is only good for emergencies. It's a good in-town car and rides nice on the highway. I also have a Eldorado Touring Coupe. For long trips, I'd take the Caddy over the SC300. For in town, the SC300 is better. The SC300 is know for air-condition problems. The Lexus V8s and In-line 6s are good engines. If you don't need a big car, the SC is nice--go for it. BTW, I think the only color that really looks good on a SC is Rallye Red, my $.02
