I love mine, and I don't think I'd do it differently next time. I originally planned to buy a modest project car as a rolling restoration project. After careful consideration, and an honest assessment of my mechanical skills, spare time and budget, I decided to get a car built to my specs so I could drive it from day one.
I'm glad I did. As a 30 year old car, it needs enough TLC to keep me interested, and there are always little things I can do to customize it. If I had bought a project, it would probably be sitting in my garage in pieces waiting for parts, money or time.
I admire those who take basket cases and turn them into works of art. As much as I'd like to do the same, I realize my limitations. For now, I'm content to drive my beautiful little car.
One of the most common pieces of advice I hear is to make sure the body is solid. The mechanical systems are pretty simple, but body work can take a big chunk of time and money.
Good luck!
