Touring car nirvana

[BSchneiderFan]

I thought I'd compile an idea running through a lot of threads and ask: what's your ideal, universal touring car formula, now that Super Touring is dead?

I'd go for three-litre engines, as many or as few cylinders as you like (though most would be V6s), rear- and four-wheel drive allowed with weight equalisation, big wheels and wings but a degree of control over said wings, and, of course, NO HATCHBACKS! I'd see a list (by no means comprehensive) of eligible cars being:

BMW 3-series
Lexus IS
Renault Laguna
Nissan Primera
Audi A4
Mercedes-Benz C-Class
Volvo S60
Ford Mondeo
Vauxhall/Opel Vectra
Honda Accord
Alfa Romeo 156
SEAT Cordoba
VW Passat
Peugeot 406
