Hmm.... "See badge on rear right"... Well yes, I can. Unfortunately the photo is taken from too far away to see what the badge actually says. Please enlighten us?
As for the comparison of a 2000 Holden to a 2006 260, yes, the price is similar, but one is a 6 year old car whilst the other isn't.
The thing that I find most puzzling is this hangup over the academic point of Dreadnought refusing to remove the 155mph limiter. How many situations are you really going to find yourself in where you have the potential to be running at over 155mph anyway? Then, in those situations where that sort of speed is realistic, in how many of them is a big, heavy 4 door saloon going to be the best car to do it in?
If you actually do spend a lot of time on Autobahns in the dead of night then I could see your point, but if you're purely talking about lapping the ring or something similar, and you have the money to buy more than one car as you clearly do, why on earth wouldn't you sink your extra £20k in to a proper racecar?

The badge says 500 BHP. I go to the Nurburgring at least twice a year and spend a 'lot' of time in Europe. You would be surprised how good a Holden HSV is around the Ring I think. I have a number of cars but my racing days are over so all road legal now. A tuner who dictates how fast he allows you to go? Hangup? I would describe it differently

Out of interest cyberface (your name not in your profile sorry) I have just sold my MG and replaced it with another HSV, a 2002 HSV GTS Clubsport. Yes the MG is a hell of a lot of a car for the money now but the 'restrictions' on tuning and the fact that it is inferior to Holdens' HSV for similar money swung it. If you fancy a drive more than happy to demo 
Heh, my name is in my profile, I just spell it without the vowels.
To be honest I didn't consider the Holden because I thought they were all 2-door coupes... didn't realise that there was a 4-door available. It would have been on the list had I known, I guess there aren't many around...
Having said that though, I don't really like the shape of the Holden and think the MG looks far better proportioned, and is a genuinely good looking car.
I take your point about 500 bhp available, I'd certainly do that if I had one. As to 750 bhp, well I'm not interested in nitrous so forget that.
I'm not really arguing with you here, the Holden sounds like a great car for the money (but only second hand). I presume you got a really duff MG (perhaps a very early or development car) because I simply can't believe that the Holden is *that* much better built than the MG. Unless the Holden is built like a early 90s Mercedes then I simply think you had a duff car. My MG is built very well and feels of excellent quality, it'd take modern Audi interior finish to be noticeably better.
It's the only thing I'm contesting here - let's forget the marque partisanship and celebrate the fact that there are a couple of *proper* V8 muscle saloons still available for us to buy in the UK, OK?
I agree the MG is a proper V8 and far better than people realise but mine certainly wasnt a 'duff' one. All credit to MG for creating a proper RWD car too. The comparison to Holdens' HSV is accurate as they chose to put a V8 in an Omega body, exactly the same principle, but the MG is not as well executed. If only they had had more time to develop it, and had marketed it properly it might have been a different story.
Apologies for resurrecting a thread that's been dead for over thirteen and a half years(!), but can anyone confirm that the 32-valve quad-cam Mod motor will not fit in the 75/ZT? The Teksid alloy blocks are light and very strong, and can be sleeved up to 5.1 litres on a standard stroke crank (I understand that stroking these engines is not a good idea, hence the 5.4 got a massively taller deck block).
They have been made to fit. There is a Two-Sixties member in Oz that carried it out. Not sure on detail but I would say mods to the bulkhead (Which is already modded from a standard 75/ZT) and possibly around front floor pan.
Lot of money, to change when a ZT 400 went through an auction house today for £10k. As said air intake and larger throttle body will see over 300 bhp.
