I owned is220d se-l 2006 for 2yrs didn't have problems apart from calipers siezed,dpf blocked due to local driving, dmf noisy, new gearbox replaced under warranty after picked car from dealer only had under 80k.i never got more then 40mpg. Was nice to drive though, sold it with 93k on clock, now got is250 auto se-i 2009 much better car,smooth quite. I wouldn't really buy another diesel as don't go enough miles.it must b good reason why they stopped making diesels.lexus brand is mainly aimed at executive market, is220d engine is avensis engine.
