Ive used the AG stuff on my seats the cleaner is good and I did use the conditioner as well I was aware of JPC comments and had just used cleaner bbut the leather started looking rather dry and I think it has improved through conditioning the pictures arent great phone camera in the dark but
as they were
with conditioner on before wiping down to matte finish
IMHO the seats are looking alot better and tighter and the car certianly has a good leather smell, in the pictures above the arm rest is about 3 months old so has the original leather finish and colour and was left untreated and the seats now have that texture and appearance. One thing that might make a big difference is model year my old house mate had a MY05 car with seats that feel very soft and supple mine is a MY06 early with aerial but still blue glass and the seats aren't as nice. The leather cleaner and conditioner worked very well on the steering wheel gear stick and hand brake as well.
