Yes I would.
I did a full color change from red to silver on my car. The car needed to be painted as I got stuck behind a gravel truck that was spewing gravel all over the highway. The insurance company paid out to have 3/4's of the car painted and I decided I was going to change the color, as the paint wasn't going to be original anyway. I too had a lot of mods that I didn't want to transfer and paying tax twice is something most people don't calculate into the equation of buying a different car, for color. Lastly, I decided if these cars ever do become collectible they will be worth restoring and I've seen some old Jags and Healeys restored that are just trashed. So this car would be easy to restore.
Dis-assembly and re-assembly were done by myself and one of my friends. It’s really pretty easy, but it’s a lot of work and time. There are also a great number of pieces that need to get painted. When the first painter I contacted looked at my car I believe he got overwhelmed with the amount of work. Another quote for paint I got was 10K. I finally used a friend of my fathers who paints a lot of hotrods and he did the car for a fair price.
If I had to do it again I definitely would. However, I would have done a few things differently.
1. I wouldn't have told my wife it would be done in 6 months. She was three months pregnant with our first child when I started. Let's just say I didn't meet the deadline set forth.
2. I would have completely gutted everything from the cabin, which looked like a tremendous amount of work. Some of the wiring and the brake lines in the cabin looked like things that I didn't think were going to go back together.
3. The reason for number 2 is I would have had the entire chassis powder coated like the DA race car build. This would have been a lot more durable in the engine compartment, wheel wells and bottom of the car. My front and rear engine bays are holding up fine but my jack points and wheel wells have some chips.
4. I would have had the chassis powder coat done in black so that the color of the car could be changed rather easily by anyone because the engine bay and front compartment could be left black.
My last piece of advice would be plan for the might as wells. Because when you do it the might as wells don't seem to end.
This is strictly my opinion from my experience.
Here is my "build".
