Use the following trick to unlock the Warthog vehicle seen in the Halo series for Autovista mode (non drive-able). You can get cars for literally a fraction of their retail price. An easier way of obtaining the cars without paying the retail price is by looking on the auction house. Here is the list of cars you will need to collect and their retail value. To obtain the Ferrari Collector achievement, you need to own all of the Ferrari's in the game that were included on disc 1. You may still end up paying millions of credits, but finding them on the auction house will save you millions more over the retail price. To obtain the Exclusive Taste achievement, you need to own the five most expensive cars in the game, all at the same time. The following extras are available only with the corresponding pack.Ģ011 Lamborghini Gallardo LP570-4 Superleggera
