"My son does that with Scoobies in his Glanza." Sounds an absolute hoot, but oh, puh-lease...
Touch of the rose-tinted specs there? Maybe the Subaru wasn't trying too hard, or maybe it was a less powerful version with aftermarket kn**head bodykit, as driven by people who don't know which way round to wear a baseball cap.
Even if the Glanza (never heard of it before, but I have now) has 4WD, which model of M3, exactly, does it beat off the line? That much power from so small an engine suggests a big turbo, which implies lots of turbo lag.... which is not good for getting off the line fast.
There's one on Pistonheads at the moment (yes, I've been digging a little) claiming 214 bhp and a TD04. On a 1.3 engine. You'd have time to make a cup of tea between full pedal and the turbo coming in...
