I would rather spend $145.00 than $550.00 but that's just me - I can live with the piping slightly darker since the leather will catch up with the piping quick enough. I only bought my bag in February and it's in perfect condition - so I sure would hate to buy a new speedy every six months. That seems a little crazy. It is only 350.00 if you get all the piping replaced too and you really don't usually need to do that. These quotes of $400.00 are incorrect and I'm not sure where they're coming from. I have a written estimate of $145.00.
It's worse now. The Speedys are 620 plus tax. Anyway, I thought refurbishing was one of the reasons you buy LV. They're not meant to be disposable bags like other brands. They used to last most people 15-20 years! These days we are probably to make them last 5-10. If you tend to use your bag a lot, it's going to get dark, and it would depend on the age of the bag and the condition of the other things on the bag.
