My first car 42 years ago was a (Lotus) 7, and my current - possibly my last, is also a 7 - a Caterham SV with a 140bhp 1800 Rover K engine. I drive it all the time, to and from work, on holidays, weekends, any weather (including snow and ice in the last few winters) - since I bought it in 2005 I've put 69,000 miles on it!
In the dry, its cornering limit is ridiculously high, acceleration - 0-60 2 up 5 seconds - will beat almost anything else on the roads and point to point on a twisty road it'll give even a big bike a hard time. In the wet, you just have to remember you're driving a very lightweight powerful car. And the roof, though fiddly, keeps you warm and dry - 5 hours driving in very heavy rain proved that to me. The heater is magnificently powerful as well!
As to practicality, my wife and I have taken it on holiday for a week or a fortnight every year since we've had it - it is surprising what you can get in it - and with a purpose-built E Bag on top of the boot there is no problem at all. Oh, and fuel consumption in mine averages 40mpg. Comfort - I have a damaged back - and have never felt a single twinge sitting in the Seven even for hours at a time.
My wife is always encouraging me to take her out in it at weekends so she can have the last word - she calls it the four-wheeled deckchair!
