well, i must say this is a hard choice. you have a 750 that you will have for 24 more months, and your not really in an area that you need a 4wd car for. for a weekend car though I would go for the LS, but do you use the 750 on weekends? what do use it for? how long do you plan to keep the LS 460 if you get it? based on what you said now, I would get the LS as its a nice weekend car.

 

I say, go for both! It's only money. A friend whose opinion I respect test drove the Cayenne, the bought the new V8 Hummer H3 and a Mercedes 600. I was impressed with the Hummer, although I am loathe to admit it. $ for $, completely unimpressed with the Benz.

 

if your used to lexus reliability, purchasing a Porsche can be your biggest nightmare you ever had.

I don't know about the cayenne but a co-worker of mine used to have a boxter purchased brand new. It was at the dealership for repair every single MONTH. I kid you not. My co-worker finally got fed up and traded it in for a brand new Honda Element, straight up traded it. My co-worker has been happy ever since.
