It really depends on what motor you are going to put in it. If you stick with the silver can that comes with the TT-01, the TT-01 will be similar to just about any touring car out there with a silver can. However, as you start to add more power, the TT-01 will quickly start to show it's limitations.
A properly set up TT-01 can hang with a USVTA (25.5) legal car. However, it has no chance of hanging with a 17.5 rubber touring car. If you plan to race it, you need to have a TT-01 class so you can race against other TT-01s. This is great fun for very little money. However, if you would like to race in other classes, look for something else.
Lots of TT-01 info is available at Michiganrc.net. We race them at Hobby-Sports in Kalamazoo Michigan.
