Graham, The one thing I have found in restoring my car is that it is difficult to compare service costs such as an interior re-trim. Too many variable and hidden problems that increase or decrease expense. If my seats just needed to be recovered and not completely rebuilt and the proper mouse hair used from the start my total labor costs for a complete interior re-trim would have been around $3500-4000 US. There are many shortcuts people have taken over the years to keep these cars running and looking good. To do the job correctly will often take more money than makes sense to the owner so.... these old cars often have a lot of very well hidden problems. I am becoming an unwilling expert on these techniques. I have chosen to try and do things corectly much to the detriment of my bank account. By the way all new leather was used on my car. Nothing redyed or reused.
