G'day d488y2 - your name reminds me of Star Wars for some reason?
Jean Christophe (JC) Bonneville is just about to rubber stamp my Cobra, couldn't meet a nicer guy. He consults to Enklemens after previous employment there. He works closely with Kenmer Cobra kits in Noble Park. Do yourself a favour and checkout the Kenmer kit as well as having a chat to Jean Christophe - more info at the link below.
Individually Constructed Vehicle (ICV)
Like me, engine and paint colour seemed really important at the start of the build but you need to build your car for compliance and that means building a car that your engineer will ultimately sign-off on. Find an engineer and a kit supplier who are keen to work with you beyond getting that rolling chassis out the door and you're 90% of the way there. It's the little things that matter, like, "will those euro 4 cats fit underneath my floor". Take it from me.
Also ask your engineer whether any new ADRs have been introduced recently. They usually have a three year grace period and Cobra builders don't find out until it's too late. Point in case, the recent changes to minimum seat height. It kicked in last July and most engineers would've known about it three years earlier. Needless to say I didn't get the memo, which equates to time and money I could've spent elsewhere.
Not meaning to scare you off - it just pays to be informed. It's all part of the fun in getting your Cobra on the road. Best of luck with your decision - exciting times ahead!
