I've had the car 11 years already and cannot part with it.
I know exactly what you mean. We had Felicity - the purple Panda "Parade" in my heading picture - for around 20 years. Unfortunately had to give up in the end because you just can't weld thin air!
My father got attached to most of his cars, leaving us with 4 wrecks, a motorcycle and two scooters to dispose of. All broken, all past repair.
A 1939 Jaguar SS drophead saloon (scarce as hens teeth), taken off the road Aug '66 for some minor welding at the rear body mounts. Never touched!
A Triumph Stag, stopped working when he fitted an unnecessary oil cooler, without a higher flow pump, and ran the crank bearings in the first few hundred yards. (I did tell him). Stuffed into the garage, and left, for over 30 years. (When we can shift brother's Herald, we might be able to get rid of the Stag too.)
At one point he had 5 cars, a motorcycle and three scooters, all broken. One day, I looked out of my window, and I had three cars, all working. That was temporary, now just the two.
I've been fond of most of my cars, but not so attached that they stay too long, most have been 2-3 years, with a classic Panda kept for 4 years and 88k miles.
But I've had the Alessi since early 2010. It will be a sad day when it gets rust in it and has to go.
