Sims 3 Motive Mobile: Best Car Ever!
The Generations expansion pack introduced a lot of new Lifetime Rewards. One of the most substantial new rewards is the Motive Mobile, which costs 45,000 Lifetime Happiness Points. Frankly, given what a powerful object it is, I think it probably should have cost more!
As with other reward objects (like the Map to the Stars or the Moodlet Manager) you can transfer the Motive Mobile to other Sims. You don't seem to be able to leave it in a parking spot for any of your household members to use, although maybe it's just that I haven't gotten the trick of that yet.
The Motive Mobile maxes out all of your Sim's needs, and it does it fairly quickly. You don't have to drive far before your Sim is at full green for Hunger, Bladder, Energy, Social, Hygiene, and Fun. The same is true for any other Sim in the vehicle, which makes it great for taking your date out on the town!
(Side note: I hate to speculate on what's going on inside the Motive Mobile, but I can't help myself. My current theory is that they are somehow sitting on the toilet, eating a snack, taking a power nap, washing their hands, and playing a video game all at once. I love the music that it plays, too - if you listen closely, it emits a sort of New Age/spa treatment "chimes and flute" sort of song. Very restful!)
This all sounds well and good, but you don't really realize the Motive Mobile's full potential until you use it a few times. The biggest benefit is that it essentially removes your Sim's need for sleep, thus effectively doubling your Sim's lifespan. Instead of putting your Sim to bed, have them hop in the Motive Mobile and drive to the gym! They will arrive fresh and full of vim and vigor and ready for a workout. Once they spend eight hours working themselves to the bone, have them take the Motive Mobile home and they will be ready to head to work.
Of course, the ultimate use for the Motive Mobile is pictured above. Tuck it into your Sim's inventory, then send them on a vacation. Presto, suddenly you can accomplish a LOT more in a three-day trip! And the Motive Mobile makes it a lot faster to get from one location to another, of course. It's like a double benefit!
