I don't agree with a few details on the last build, painting the scuttle bulkhead and the Dzuz on the top bonnet. Otherwise, I can't find any fault in the color. The paint is good and to recover the car for no other reason than authenticity is just more money and trouble to fix a non-problem. The original paint is gone so nothing is being restored. The only good reason to change the colors would be to suit the new owner, not the previous owner.
These cars have a curse that follow them and it is very present with this car. As it is well stated in the Simple Sevens history page, a previous owner, Brian Herrman, started an extensive restoration and "ran out of steam". Then the project languishes for years, about 23 years, until the owner realizes he is no longer capable of finishing the project and sells it off. Don't let this happen again.
I would recommend improving on the small things that need done, but keep the car a driver and appreciate the investment the previous owner made (Jim Downing?). What is his story?
