How much to make it road legal?

It's not that bad. Just the windscreen needs a redesign for it.

I think it's beautiful

TVR Tamora. Better than a gym?

Price is one of many possible ideas.
I think one of the best could be Power-To-Weight.

Or a classification based on average Weight, Power, Torque and Power-To-Weight.
We have classes for race vehicles so why not road cars. Goods vehicles have a few classes already.

Raises the question: Should cars worth over $50k, $100k & $500k have extra licenses and training to prove you can drive them? Police, Taxis and Chauffeurs require it for less.

Hopefully not a lie.. http://tvr.co.uk/

Skip the middle man and go straight to the designer..

Any TVR. In this case a Tamora..

Looks like a Triumph Spitfire mated with a Miata.

You'll need the door open in a GT40. It's a very tight fit in there ;)

There is no best, imo. All museums have something unique/special inside. Whether it's a private collection or an actual business.
The Haynes Motor Museum in Somerset, UK has a 'red room' with a huge collection of random cars: http://www.haynesmotormuseum.com/

'bout time they brought back the 3.0R.

The GM badge kinda ruins the mood.

The website encourages you to download the models, build them, and then build upon them to design your vehicles.

I guess it's mostly a Europe car. I've only seen a couple in the UK.

BMW GT line. Not many around but they still manage to sell them.
