Jonas, you will find on this site, some questions become a little bit dicey to talk about in an open public forum. You are best off talking to people in private email about some subjects, especially when it may influence your decision on who to have build your car.
In fact some posters will only respond to such questions in private, to avoid the honest scrutiny of what they might say, and the dishonest scrutiny of people with an agenda.
Frankly, your best bet is to talk to people who have owned different manufacturers cars.
So, talk to Jim Ward, about the differences in Vintage versus IM.
Talk to Stan Galat about the differences in JPS and IM.
Talk to me about the differences in IM and SAS.
Talk to Alan Merklin about owner built cars and how to evaluate them.
There are others, but these are people I can think of off the top of my head.
This is how you will really find things out, Jim isn't going to say one bad thing about his IM, even if there are things he would like different or that he has had problems with, and you really can't expect him to say anything bad. You can expect much the same from me, and anyone else as this isn't like buying a car from GM. People are buying these cars from individuals and have a personal ongoing relationship with their builders.
Simply put, DON'T believe half of what people say about the kind of car they currently own, everything about a kind of car they used to own, and nothing about a car they have never owned.
