That's funny - I have been having similar thoughts though and may go for it ready for next year's 'motoring season'.
I occasionally have thoughts about an EV. But I'm a private buyer and the sums don't add up for me.
Or maybe a hybrid. I like the idea of electrickery round town but I can't get excited about a 4 pot. Shame MB never did them as a 6 as that's my ideal combo.
Or there's the E43. Or even the E400d. They're both stonking cars. But they're still high £20k's.
I had real reasons to go 200SX => C43 saloon = C43 estate => 211 E500 estate => 212 E500 estate.
But there's nothing obvious to tempt me out of my car with a clear benefit at a reasonable cost.
I just can't decide what to do. So I just end up doing nothing.
