I'm a college-age classic British car enthusiast. I own a 1969 Triumph Spitfire, which was my first introduction to the hobby and it has been a good five years living with it, and I look forward to many more happy years. However, it is my goal to expand and fit a few more classics under my belt with my Spitfire, and as a fan of the original S1 and S2 Lotus Seven, as well as being eager to tinker, I'd love to build a Locost Seven with vintage equipment (either a Ford 1600 Kent engine or BMC A-Series, Ford T9 gearbox, skinny wheels and tires, Lucas lamps, Smiths gauges, and other assorted classic Seven parts).
However, I have a fear of even considering starting a project in California (I'm in the Los Angeles area), with all of the complicated registration and smog regulations, and the daunting task of obtaining an SB 100 - which reminds me of registering for college courses, where you try to register first thing and get booted out because of limited availability

Smog won't be an issue because I plan on using pre-1975 drivetrain components, so I am thinking of parting out an old MG Midget/AH Sprite or small Ford for the engine and other useful items, and using the VIN and ID data from that vehicle on the build (so in essence, it would be like re-registering an existing car, only it doesn't look the same). Or should I just brave the SB 100 process? I'm hoping to start a build in the future, as it would be a great introduction to building a car and cheaper than restoring an original Seven (which are too expensive for my budget, as are the Caterhams).
Thanks for your help!
