Ahh, of course. I forgot about the land rover. Once you're not running out of money every month, the rental cost (or purchase cost) is mostly irrelevant, but while money is tight the costs may be worth considering:
The land rover costs $150k, sells for $100k, and has $25k rent. If you buy it, use it, and sell it without the month ticking over, you effectively only spent $50k. If you keep it instead of selling it, you spend $50k every two months on rent, on top of the initial $150k. If you don't use it in those two months, you're burning money (not a lot, but if you keep running out, it could make a difference). Of course if you need it at least once a month it is more economical to just rent it.
P.S. The fun thing about the Dragonfly is that despite costing $300k to buy, it has a lower rent ($20k) than the land rover!
