Word to the wise: Price some stuff first though before hitting your local upholster.
The several I checked in my area wanted half again more than what a prefab kit cost.
Them: $650 (cheapest I could find, and they wanted the whole car for a couple weeks, not just the seats for X time, you know, in case I couldn't figure out how to remove the seats all by my lonesome.....)
Prefab: $420 (including delivery)
One even insisted it would take 12 yards of material to cover the seats in marine grade and the price they quoted for the stuff was almost double what it actually cost off the rack at the store that sells it. (I guess they didn't think I'd actually go to a place that sells it and check)
Oddly enough that 12 yards just happens to be the size of a full roll of of the stuff, and if it takes that much to do those tiny seats, I'll eat my hat. (I faked up a set for 1 seat using under 3 yards incuding all the pleats and piping. Now if I could just sew consistantly....)
Not to say upholsterers are bad, just do a bit of research and go in with eyes open and at least an idea of what those things should cost before you end up with that one who's just looking for some dummy to burn for a pile of money.
