I have received a quality education on this forum regarding leather furniture, leather grades, care and maintenance, etc., etc. However leather upholstery manufactured for use in cars is a complete mystery. I have learned only that the user environment is so different from home upholstery, i.e. getting in and out, weather conditions, subject to intense heat and/or cold, etc.

Can any one shed light on what one can expect to get if they order a car with leather seats? How is a seat constructed? Is top grain used? By-cast? Splits? Vinyl? We're not talking for a Mercedes, Lexus, BMW or Porsche here, but for a family mini van.

Your experiences with leather seats? We tend to keep our cars for 15-20 years.
