Then you bought the mega cheap stuff mate (or we MASSIVELY get shafted here in Adelaide) .... I have been to several reputable places here in SA and for any sort of decent leather retrim for the things you are talking would be almost $10k. I was quoted $6k for just my seats, door inserts and steering wheel, at one place using top quality Italian leather. The guy was talking about 30 hours labour @ $70 per hour for a start - you paid half of that amount with no material, which is the major costs involved.
On that front, can anyone buy coloured cows at a decent price? I might grab a large piece of leather if I can find one at the right price, and get seat by seat done, one at a time.
