Expect to pay anywhere from $150-200. I couldn't get Tower Hobbies website to come up, so I couldn't check there. On Hobby Links Japan, they are not listed as XB, or Expert Built. One is the Enzo Ferrari and another they have listed is an Opel DTM car. The DTM car is one of the older XBs, built on the TL-01 chassis. The new XB's are built on a TB-01 chassis, a bit more stable. The problem with the RTR cars, they generally are not very adjustable. To make the TL-01, for example, more adjustable (and a bit more stable), you also need to buy the Long Suspension set, about $40 or so. That will give you more shock mounting options and ads sway bars. You may be able to pick one up on eBay, I have seen them there before.

Thay can be made to go more than 35 mph, depending on gear ratio and the type of motor and batteries you drop in. You can probably get a pretty insane speed run out of an 8 turn motor and 2400mah-3300mah batteries. You don't have many gearing options with the TL-01, and the way the chassis is designed, motors can get too hot. Not sure about the TB-01 though, don't have one yet. Check out the forums on rccaraction.com. They have an area where people talk about different kinds of cars. A TL-01 forum, an HPI RS-4 forum, etc.
