Thank you. I am looking at a RX350 President, but I guess its similar to RX450 in terms of suspension. Labor is not an issue, i will probably get quoted about 40 GBP / hour at a friends place. Parts are, since I almost have no part numbers for the normal suspension. Found the air suspension onces + the air compressor. I mean, even at what you quoted with prices, swapping the entire suspensions seems cheaper than 1 airbag replacement + labor 🙂
