The Mono is beautiful, but you can never scare a passenger/take someone along for the ride.

Very true.

Whilst I usually drive the Atom on my own it’s great fun taking people out for a blast. It’s a different experience demonstrating the car to someone else rather than trying out things for yourself.

Passengers always seem to insist on paying for lunch\coffee as well.

I was meaning like a Caterham, but not a Caterham. 🙂

Or something in a similar vein that can be done for under 10k

That doesn’t look shit!

Ahh scratch that! Didn’t see how old the advert was 🙂

There are (or were) quite a few Caterham /lotus 7 style kit cars about though.
