I use mine as an occasional driver doing 10 miles to work and back
Depends really what your drive is - stop start can be a pain with the clutch pedal not been so light - others might feel different!
Car parks with ramps means a couple of scrapes at the front plus a couple more turns to park up because of the turning circle
On open roads its fantastic especially with the kw suspension upgrade

which seems to make even wet weather driving a doddle
Bills wise it really depends on how much and how you drive - I reckon on something needing a major repair every 2 years at 1k a time. That said they are fairly reliable with common faults been coils, but other stuff like air con or power steering pipes oxygen sensors ball joints can fail on top of routine parts like clutches brake discs cambelt etc
Mpg in traffic is 22 mpg longer runs is 30 though since my second car is a 5.5 litre amg Benz you can guess I'm not too worried about the price of petrol!
Be warned the attention you get can be fun can be a pain - I get bus loads of Chinese tourists in Hong Kong flashing away when they see the car - that plus dumb mini pooper drivers trying to race
That said I've had mine for five years and love it- it's that feeling owning something special compared to the rest of the cars in the car park. Firing it up and the janspeed exhaust sound bouncing off the walls. Driving the nuts off it with the sound of the engine roaring away just behind your ears!
That and always finding some new road to test your driving skills and high speed cornering means your often taking the long way round when popping down to the shops
