I can't, and won't comment on the details as I truly don't know. What I will say though...it's common knowledge that official paid $75,000 for the car, and import will have been a few k. There's then the fact that it had time circuits missing (2k worth) and lots of the original castings were removed and replaced with cheap parts, unknown to him after he visited. I have calculated that he's spent around £70k, possibly more! The flux bands were replaced, new neons, all new interior, newer castings. He was royally ripped off by J, and even though he wouldn't show me the same courtesy, I felt sorry for him, genuinely. That doesn't stop me from knowing the truth now though, that he is an inconsiderate, self centred, disrespectful, lying butthead.. He still to this day shits on everyones cars, even on his own website and on Twitter.
What J did to official, sounds 10 times worse than your dealings with Bozzy. Even with the bits you have had to do (small bulkhead bits) it's infinitely better than THE bttf car, and for a damn sight less money, hence him pretending to be pally with you so that he can obtain the parts or details to make his car more official like the claims. Heck, if his car was so official and perfect, why did he remove 90% of the cars parts and replace them?
He will use the detailed research from your car to make his near what he says it is, then use it as ammunition to shoot you down when people try coming to you for events. I'll place a bet now, that once you get off the ground, that he turns on you also, especially if he doesn't get his commission.
When all said and done, a lesson in life is to never pay up front for things as peoples opinions are all so different. Truth be told, I had a few of the same thoughts you have have with Bruce myself. When it arrived, there were a few things wrong and I went into 'perfection mode' and had a bit of a whinge. I now really regret that, as the more I look at the detail of the car, the more I truly appreciate just how much work has gone into my car and of course yours. Bruce is a true gentleman, and put lots of effort into making it weather proof for me. I have spent a small amount of money doing a few things and just generally cleaning up the car, and with that taken into consideration, it was still a good deal and a LOT less than our favourite friend spent on his car.
Enjoy your motor (there's a video of you on YouTube on the roads btw, uploaded this week!) but do take care. Once all your info has been sent over, there will definitely be mood changes and you will begin to discover nasty downtalking, just as I have myself from people who have forwarded me responses of dirty sales tactics..
