Not Much To Add
Yah, that 56k miler seems a legit contender. The leather kit must be close to a grand in itself. I like if a seller has kept receipts for things and generally shows pride in ownership with consistent maint. items (as that seller seems to have).
Last thought: I always focus on buying the car, not the price. Get exactly what what you're looking for whether a garage queen or a fixer-beater. Then put a fair value on it and be prepared to buy ---- or walk.
