Personal oppinion. You have a very low number Mallett with very few miles on it. The closer you keep it to stock the more it is going to be worth down the road. I just sold mine a few months ago. The value on #005 will grow as time goes by. I would also recommend you insure it for claimed value as quickly as you can. State Farm did mine but I think Rob got a better rate from another company.
If by some chance you want to go with the wheels that were designed for the car, I have the Cad drawings for them. I had two made for mine.
The sound is fantastic, you will love the car.
Be careful with it. They are a lot different to drive than the GXP or Redline, as any V8 conversion would be.
