This is actually right up my alley, There are several leather companies out there which most shops use. The most popular ones are Katzkin and Classic Soft Trim, ask which they use if you plan on getting leather seats, in the New York... Schenectady area we charge 1499.00 for front and back seats and door pannels, leather and 60 bucks more for two tone and embroideries... But you can probably ask most shops to give you a better deal. If you say you will pay in cash you will usually also get a better deal. Classic Soft Trim makes the best leather, we use it and its top notch quality. Also depends on who installs it, As far as wood dashes, they usually retail installed for about 400 - 26 - 36 piece sets, and about 300 for 14 - 17 piece sets, I just ordered a blue carbon fiber dash for my own car. I ve got a blue sedan. The price on leather you can usually get knocked down like i said if you try. But as you understand everyone has to make money.
