EVO??

Collectively, Tamiya, Hasegawa and Fujimi have pretty much covered the EVO range in 1/24th scale, from II through IX, in a broad range of road, WRC and racing configurations. 

Tamiya have EVO's V-VII in WRC configuration plus an EVO VI road car.
Hasegawa had a range of EVO's II-VI in WRC configuration, some of which include PE parts, and are difficult to find (here in Australia at least)
Fujimi, I believe, have road versions of EVO's III (?)-IX, and a number of "racing" versions.

There is also a fairly "light" 1/24 EVO VII WRC by Heller/Airfix, which is so basic it doesn't even include interior door panels (Instructions tell you to paint the inside of the body shell black) 

As far as I am aware, all of the above are "curbside" kits and none have engine detail apart from what can be seen from underneath.

Wow thanks! that was quick and full of information. those fujimi kits look like what im looking for, has anybody built them? are they worth building?  despite what they say over on the aircraft forum ive learned better, you auto guys are allright

Sorry - wish I could help more...

The above list came from memory, so I may be off on a point or two. Of the list above, I have Tamiya's EVO V WRC and the Heller/Airfix EVO VII WRC, both of which are still "in the box". (compared to the Tamiya offering, the Heller/Airfix kit is positively stone-age)

For some reason, car kits command premium prices here in Australia, (asking price for the Fujimi EVO IX's at one of Sydney's major hobby retailers is a mere 58 bones - appr. $49 US) I may be temped to order one from Luckymodel, which should work out to be about half the local price.

I wonder why so expensive down there, alltho i guess kits are pretty pricy everywhere now days
