The problem with your application is that your car is european,
Most of their sponsors if you hadnt noticed are like Year One. Mostly domestic american, non metric measurment cars the parts the like.
i've only seen them do ONE import, that was a civic and they gave it a gay looking paint job and a body kit, however, they did do a good job on the dudes engine rebuild.
I dunno i bet they wouldnt do it because of their lack of parts that could be accessed in 1 week for a jag, especially that v12.
i'd be really warry if someone told me my supra had been with them for 1 week, i know it would look cool, but it'd probably be bright green with racing stripes a wing and a rebuild done by someone who's never worked on a 7m. Hell, they'd probably buy a new longblock from toyota and try to throw a diesel turbo on it and call it good with an msd ignition.
