Pat, as I discussed with you on Saturday night (lovely GF, Brenda by the way) the GTS will suit you.
As you know, we both have taken a near identical tack with our cars over the past 10 years, and I know, you will love this car. The reason for it is not out and out performance, its the sheer presence of the thing. When you drive it you feel like your piloting the Starship Enterprise, its just epic.
The GTS is a very Germanic car, without a doubt, Maserati have done their homework with this one and are balls out gunning for the Mercedes AMG, BMW M and Audi RS market and they have done a fine job without loosing that Italian'ness we all hanker after.
If you can find the funds, go do it, don't think twice.
