Re: Porsche Cajun crossover
It's a Porsche thing, they've done it forever, it's sort of a nostalgia thing nowdays. Porsche 911 buyers would scream bloody murder if their cars didn't have the key cylinder on that side.
I liked the idea of the Cajun a lot, and I'm a big fan of the Cayenne. But, it's going to be pricey, it's going to cost more than the Audi Q5 (which is a very close cousin of it - tuning and powertrains may differ some, but it'll be the same platform). That puts it into the "starting at around $50k" range, which IMO is pretty much Cayenne money.
If she's into the fuel economy thing, have her look into the Range Rover Evoque. Super nice, very classy, very efficient. I looked at them, but I couldn't get past the price point for how small it was (part of the reason it's fuel efficient is it's small).
Mercedes is also coming out with a GLK diesel, that should fit her bill as well. Audi and BMW will likely not be far behind on the Q5 and X3 (both of which are very nice vehicles btw - and definitely better than the GLK IMO). BMW also has the new X1 coming out, slightly smaller, faster, and more efficient than the X3.
I looked into those and a lot of others, but got the Jeep. Remind her that the amount of pollution she will cause driving it to and from work PALES in comparison to the amount of pollution caused by manufacturing taking place all over the world, and parts having to be shipped across the planet for assembly at different locations. With the Jeep, it's mostly going to have US parts and manufacturing, as opposed to being round the world.
It will at least get her all rustled up about being green by buying an import that saves gas.
EDIT: And as far as the Cayenne goes... it comes in many levels with different oomphs. The base Cayenne is the Touareg's V6, and it is a dog. A nice ride, but not fast. The S ups the ante with a Porsche V8, and is nicer, older models weren't hugely fast but were entertaining, newer models are fairly quick. Then you've got the Turbo and Turbo S, which are monsters that eat SRT8s for breakfast. The GTS is IMO the best model of all, as its above the S in power, but is tuned for sporty handling. Fast enough to be fun, but fun enough to keep you smiling. It won't outrun the Turbos, but it's going to be more fun and may out handle them.
