Nice writeup! I, too, was completely smitten by the MTW when I drove it. I still hanker after one, and if money allows I might well treat myself in a year or two. But just like you, I have to say my 4/4 is absolutely perfect for my needs.
I shan't be getting rid of it, it's been with me for 12 years now, and it's just coming up to 100k miles - although in truth there's not much left of the original car now, the body tub, seats, propshaft, crosshead and cowl are original, but that's about it :-)
