The shocks are the same regardless of facelift or pre-facelift so I don't understand why the price would be different. I replaced all of mine with Arnott air shocks from the US which cost me £2,400 with shipping. If I was replacing with conventional springs I would buy Strutmaster kits also from the US, about £1,400 delivered to the UK. The coilovers from eBay etc, especially adjustable onrs are something I would avoid. Strutmaster use KYB which is what Lexus original shocks are. Not a particularly difficult job to replace them.
