Experience is by definition a personal thing which means you can make that part of the book whatever you want it to be. For some people it will be the oft reported lamentable build quality, the rattling ride, the flexing body. For others it might even be a sentimental link to a stage in their life, an event like marriage.
Unless your target audience is the membership of this forum ie Morgan enthusiasts, I wouldnt go too strongly for the irrational emotional baggage that Morgan has for Morgan owners. Its a car not a spouse.
