That will likely make it more difficult to register in CA. Good luck with sale - it certainly is a unique car.

What classification was the car registered under in MA? It appears that cars can be registered in a variety of ways such as model year, replica car, speciality construction, etc... Or was it just titled as a regular car? https://www.semasan.com/semaga/TagTitleToolbox_MA.pdf

I wonder if it would be possible to register this car in CA. Do you have any pictures of the original build? Or history of how it was registered from 1978 onwards California DMV will ask for proof of it being assembled as a kit car.

I'll be there in my X180R

Congrats - you will have a fun time with the car when its done. Its amazing how quickly you get used to the power. When I first drove it I got wheelspin in 3rd and felt that was more power than it would ever need. But a year later I was plotting how to add more power. :-) For the exhaust I just had a off-the shelf Hushpower welded to the collector and it worked fine. It would not pass the 92 dB at Laguna Seca but was under a 100 dB.

Main thing for me would be the engine as new blocks are NLA and junkyard ones are pretty pricey. I'd also verify that the tuning system is something you can actually use/understand. Mechanically the WCM is pretty simple to work on and at that price I wouldnt worry about things like the brake bias and diff bracing as they are easy enough to add on later. When looking at the car I would make sure that the footbox is large enough for you to use as it becomes smaller as the pedals go deeper in and can be a problem for folks with large feet. I wear size 14s and could only drive with driving shoes. I had mine for several years (as you found on my blog) and had a great time. The Ultralite has the right level of power for me and is very accommodating of taller/larger drivers. All the best with your search.

My SB-100 Stalker MSO said "Replica/ Facsimile of circa 1962 Lotus 7"

I registered my CO-built and registered Stalker in CA in Dec 2019 with zero issues. The OP here is specifically having trouble with Caterham registration. For cars that were built out of state you should be using SB1578 which is the companion law to SB-100 that uses SB-100 sequence numbers but covers cars from out of state. You can try to register a car from out of state as an ordinary vehicle but I imagine you would get in trouble if CA ever figured it out. An SB-100 registered car will likely also have better resale value as it can be bought and sold as a regular car in CA with zero risk.

You still have too go through sb100 if you are registering a kit car from out of state. It's pretty much the same process as if you had built it yourself except that you list someone else as the builder. Will still need photoos and receipts for chassis, engine, etc...

Hi Folks, it is indeed MightyMike's Stalker. I originally bought the car with the intention of making it a track car but realised it was just too nice a car to make the changes I was thinking of. In just 18 months road legal in CA I put on about half the miles that I did in 6+ years in my old WCM Ultralite but I just cant justify it as a pure street car since my wife cant drive it. In the end I decided to let the next person enjoy the Stalker as a truly spectacular street car instead. Current plan is to keep fixing up the Lotus X180R that I bought last year. I do imagine another Seven in my future - perhaps a bike engined lightweight edition to try something completely different from the Stalker.

Have you considered a V8 Stalker? Truly ridiculous power without too much of a weight penalty

Thanks xcarguy

Hi Folks, I have discovered a fair bit of play between the steering arm and the knuckle on my stalker. It looks like are only attached on the ball joint knuckle so I cant just tighten the nut. The play is on both sides and is greatest on the left side. Is this a known issue and are there any suggested fixes?

Looking forward to seeing it running. Out of curiosity did you consider the RST or Hartley V8s as engine options?

Rear is just too stiff and bounces around. Need to play with spring rates and shocks.
