On-road BL project

[BrianG]

Now that Revo2 is done, I'm looking at doing another conversion. This time, something a little smaller than 1/10 scale, but bigger that 1/18 (if there is such a thing). This one will be strictly on-road (parking lots and the like). I want 2wd, have low ground clearance (~1/2"-1" max), have a very firm suspension, solid frame, ease of maintenance (where getting to one part does not involve disassembling the whole thing), and want a wide stance for cornering.

What is a good buggy-like platform for ease of finding OEM and aftermarket parts? I don't want something that will be discontinued tomorrow where parts may be hard to find.
