if you don't want a true touring car body, then Proline's Opel Calibra (should be Astra) V8 and the HPI Mercedes CLK-GTR are good.
The tourers that I like are the Mercedes CLK DTM and the Volvo is pretty good too. But my personal favorite touring body is the Vexhaull Vectra.
I've found it is quite a bit of a mix between the old stratus and the Accord. if you want more turning everywhere on the track at the expense of a little stability, then the new stratus would be good. (ugly as heck though)
