2012 Vauxhall Maloo review - Car and Car-Buying News - What Car?


425bhp, 6L, V8.
It's faster and accelerates harder than a BMW M3.

Ok, it's a tad expensive at £51,500 but if you use it as a commercial vehicle you get back the 20% VAT (£8583) and so the net price is just £42,917.
America could have had it but because GM closed down Pontiac, it never got the Pontiac G8 ST.

I'm wondering if Vauxhall will ever import the 3L V6 variant. I don't think so but maybe Ireland might get it if Opel decide they want it.
