After 5 months my wait is almost over. My new GT500 has just finished being converted to RHD, by Mustang Motorsport, and only waits for the compliance plate to come through before I can take delivery (and see it for the first time in the metal).
Additional work I've had done (so far) includes window tinting, install of invisible car bra, 20" Alcoa's, lowering springs, adjustable panhard, and new UCA.
