Having driven my car yesterday for the first time since October, it confirms by opinion.
All of it's modest power is useable, and because it's not as cosseting as a modern car, it feels like you are going faster. Mine has completely stock suspension and it works. It is so small that it can be placed with pin point accuracy, but also easily adjusted with either the throttle or steering when pushing on.
Comfort and performance wise, it would be possible to use one daily, but my concern is always what if it has a bump? Even with agreed value insurance covering the cost, parts are few and far between, so the difficulties of repairing it could mean its game over. I think they need to be enjoyed on a sunny day with the sunroof open and a Don Henley cassette playing.
