I've had many of the well-grounded gripes mentioned by others - most recently, close to $1K to replace an electronic throttle(original unit's design led to idle pulsation!!!),... but I still think it's a better option to maintain a paid-off car than to splurge on a new car. I don't know much about the long term rust durability on the S80. Here in Ohio, a lot of salt is used on the road. To keep the body in good shape, do you think a Ziebart undercoat is worthwhile? Would value your opinion. Thanks.
