As is so often the case, this thread was pulled way offline, whilst not necessarily being hijacked. I'm all for it personally. Within reason. Good banter is cathartic!
But, the OP was asking, unless I'm mistaken, if the car was a good deal in comparison with other GTSR's on the market. Not whether he should by a far lesseer car and mod it to get similar or better perfomace. Likely coupled with a sinificantly impaired factory warranty, and possibly questionable driveline longevity. Not to mention an immediate and 100% write off of the cost of the upgrades and probably accelerated depreciation of the underlying base car.
What I'm not keen on is people defending their own decisons, by lambasting anyone whom dares to take the safe and easy road, i.e in this instance buying a HSV GTSR, rather than taking the road less travelled and modding the crap out of a N/A Holden, or heaven forbid FI!
It is not for us to ride in on a noble black steed, to save all from their proclaimed naivety, declaring with rigour and fervour the folly of their decsions.
Unless of course they ask. Then, a balanced response, as opposed by a cycloptic tirade would be warranted.
Your honour.
