Tamiya xv-01 has a Subaru STI hatchback. The body actually comes with a rear wing and a scoop, albeit a roof scoop, but I have seen people mount it on the hood.
This car is very scale looking.
It is more of an on road car capable of ripping some gravel, rather than say a buggy and rocks. So keep that in mind. It can reach something like 2.5cm (~inch) of ground clearance, if not a little more.
I too wanted a rally car, but in the end, I drive my car on the street 95% of the time. You can really set this thing up like a touring car. Which I learned a lot about suspension and differentials.
Parts for Tamiya are limited, but I think better availability than Kyosho. I try as much as possible to order form local-US, but sometimes ordering from overseas is needed for some parts/upgrades.
Nitro would be fun. But I think loud and messy for my neighborhood/workspace. I considered the HPI cars, but like all the other people have said, HPI as a company is still around, but very much in flux when it comes to support for their vehicles.
My pick was the xv-01, for scale, Touring car setup, and vast body selection (190mm/200mm) Tamiya and HPI bodies.
For all out ruckus, maybe the HPI and Kyoshos. They are more the size of short course trucks.
