How exciting is it to drive. Hmmm, what about Jeremy Clerkson's review of the Mk 3.5 (Sunday Times, 20th December 2009) 

'The fact is that if you want a sports car, the MX5 is perfect. Nothing on the road will give you better value. Nothing will give you so much fun. The only reason I’m giving it five stars is because I can’t give it 14.'

Or his review of the latest Mk4 (Sunday Times 22nd May, and apologies for this particular quote):

'This one looks as if it means business. It’s an attack rabbit. It’s a cure for depression, this car. You just can’t be in a bad mood when you’re driving it.'

Now as it happens we might be selling ours sometime soon to get a Mk 4; ours is the Mk 3.5 Roadster Sports Tech, so the sports version of the worlds best selling sports car!
