When Colin Chapman, the late visionary genius and founder of Lotus Cars, coined the maxim “Simplify, then add lightness” way back in the ’60s, he probably had no idea it would become a significant part of the automotive lexicon. And he most certainly could not have imagined it being used to refer to something like this street-legal, open-air kart based …

From the result I'm surprised this guy wasn't a professional fabricator when he started the project...also might be a true mountain biker since that bike could cost more than the car! laugh

I like that !!!!!

 

I would add a partial cycle fender to the back of the front tires and to the front of the rear tires.  Thinking about it more I think you would have to do that for it to pass the yearly inspection to be road legal in my state.

I have yet to see one of these homemade, tubeframe monstrosities that is remotely attractive. The worst of them are deathtraps with no sense of engineering, triangulation of structure or even raw strength. You may say that they are functional and light but why make something ugly when you can make it attractive for the same effort and money? no

Did I miss in the article how much the car now weighs? I couldn't find that nugget.

Ugly is personal. Some probably prefer it this way. As for triangulation, it looks like this guy did a good job. It may be safer than the factory car. Surely stiffer.

Everyone has different taste but bashing someone's hard work out of the gate seems kind of Bob Costasey. 
 

The builder showed a lot of skill to build that. Nice job Guy who built the car, you can't please everyone.

You call that a Boxster?

If the Judge Judy part was a typo, keep it. Its accurate.

I'm honestly not sure how you could make something too much better looking than that with only tubes. Depending on how badly it was wrecked, I'm not sure it would have been the same or less effort to repair it properly. Plus then it still would have looked like a 986 boxster, which...honestly this looks a lot better.

 

I found a video elsewhere that claims 2150 lb. That's lower than I would have thought but seems believable.

This isn't Youtube or some such. If you like to say things just to set people off, take it elsewhere.

Having built an Exocet, I can attest to how much work this would have been, starting with a full car and having to fabricate your own bits. The result obviously shows a lot of love and effort, well done!

I like it but, I have never been accused of being sane. I would drive it just about everywhere.

Yeah, me too.  Author Zach Mayne went on and on about how much lighter it is, then never told us what it weighs.  That article could have used a spec panel like most of its kind do.
