Hey! I'm looking at a 2008 Lincoln Town Car with 82k miles. It looks to be in really good shape and an older couple who did the maintenance on it. I heard that the passenger side can leak onto the floor board. Exterior and interior look great, but I did notice floor mats and some of the carpet looked worn. Do you know if this is just dirt and wear overtime on a light interior, or could it be from a water leak? Also anything else I should be looking for in person when I check it out? Any help would be greatly appreciated, thank you!

ps. Do you think the steering wheel and armrest can just be cleaned or is it too far gone?
