The latest version HSV Maloo will have the most power, and should be eligible for a supercharger from Walkinshaw if he can be bothered (Power to ~550KW on a 6.2ltr, apparently). That said, if he really wants the silliest Holden ever made, and can live with a sedan, they did put out a limited edition sedan with a 7.0 litre V8 a few years back, although he'd have to find one from a private seller.
Considering NAMOR is a large size, and is having boots made with few real seams for them to join several pieces together, I imagine it'd just be that Vass is using larger shells, which have lower quality areas within them? It was ordered and delivered as shell, sounds like an honest mistake/material defect rather than something malicious.
Had a pair of pants made up at John K Tailoring on Magill road I've been very happy with. Took a pair of existing pants in and specified the alterations I wanted for the new pair (Added ~2in to the rise, etc), very impressed. Have not had a jacket made locally as I don't have a need. If you're looking for decent value suits, Adelaide Suits Direct in the CBD/South Road do decent half canvas suits at ~500 (Can generally get a second pair of pants in there too).
For those in Adelaide, looks like we have a local MTM shirt operation recently opened: http://fineaustralianshirt.com.au/ or chriskisna.com.au starts around $150 for a single shirt, drops to 130 for 3 or more.
Have ordered a white OCBD, delivery is in 3-4 weeks. Will report back with thoughts/pics on receipt of shirt, but was impressed with the fitting process and attention to detail.
