I like your thinking there fella! You have decided to purchase a fantastic car ( not that I'm bias!) yes it may cost a bit more to run than some other cars out there but the sublime enjoyment from the pure luxury is great! Unless you are really really unlucky you should'nt be spending much on parts and you are gonna get a lot of car for your budget! Don't be put off by any cars you look at that have poor finish on the lacquer on the alloy wheels , there were cars getting their wheels changed under warranty because of this and sometimes more than once! Could be a good bargaining tool.
you are right about the toys, my 11 year old 250 SE-L has got radar cruise, voice control of entertainment and realtime traffic SatNav!!!
