After having an IS300 and then moving to the RX i found it was becoming more impractical day to day.
Crawling round the worst part of the M25 twice a day and getting sub 22mpg, plus a 1k warranty claim for the air suspension front strut made me change my mind somewhat, plus spending over £400 a year on road tax and spending £80 on fuel every 5 days.
Great for the dump run, but when there is just me in the car 95% of the time you seem to think that there are downsides apart from the comfort and driving position.
So I moved on to a totally different car- an Audi TT, yes, smaller although can still fit the wife and one of the kids in, but in terms of fuel economy- over double what I was getting in the RX and Road Tax is £175.
Build quality is on a par with the RX, has all the toys including a much, much better Sat Nav and phone/ipod/SD Card (x2-64gb) set up.
Sorry to see the car go?- in the recent poor weather maybe, but general day to day?- not a bit....
This is what the RX was traded in for...
