Maybe a 6 cyl torana that has been mocked up with the SLR5000 body kit?
Each to their own. But I'm dead against "wolves in sheeps' clothings"... Look up the word 'affectation' and consider if you want to be considered such. Only my 2cw.
The only recommendation that I can think of is that you wont get 'muscle' for the budget that you've specified, that's not to say you can't get something with street cred: which i assume is your intention. You can get some sweet 1200 utes in that price range (depending on how tall you are: <6' suits 1200 utes IMO
). Or you might be able to pick up an old falcon or kingswood, if you are 'johnny on the spot' and are looking and ready to pounce when that good one comes up for good money. Also I recently saw a fully pimped 180bsss go for around 10G, bit more than you've specified but....
OOOOOO one thing has just come to mind, me growing up with Ford blood pumping through my veins: XHII xr6/8 utes in good original condition is in your price range. IMO this is the last credible ute that ford made (single body not split cab:tray) before they sold out, us, the consumer for pathetic production efficiency. And they are a sweet looking ride as well
Good luck with what ever choice you make.
