And now you may have a point. I didn't know there was a difference between the VIN and chassis number!
Because I no longer have the original frame, I wouldn't be able to check.
I think we should all, including me, cut people some slack about many of the finer points about our cars. I've been impressed by the differences between the S2 and TC and even more impressed by my ignorance of the large number of differences (They look pretty much the same and their only real difference is the motor, right?). I've had my car since new and I rebuilt it about twenty years ago so while I might have some insights many might not have, I still find a lot of things I don't know.
I get some people, who seemingly should know better, who think the bump in my roof was standard. Some people relate the Lotus Fords of F1 and Indy and think that's what I have since it says 'Ford" on the cam cover. People ask me all sorts of what I consider strange questions about the size of my engine or the number of cylinders. The guy who sold me my first one said he used to race in F1 and that the front anti-roll bar just needed to be tightened when the stud had broken off the shock. I was told many years ago that the rear toe was not set accurately at the factory and could have been as much as 1/4" or more (I've since disabused myself of that notion, but of course it's irrelevant, too.).
In other words, put your pie away and save it for if you or I ever see the salesman who told me he drove F1!
