But let's face it, you and your mrs are thoroughly bored to death with the Lexus and at some point you will have to replace it anyway. Just a question of when, not if.
Well I was bored of the Lexus after 6 months but the only time I drive it is to fill it up every 6 weeks, and I'm not swapping the X for a 3 .
My wife is much more sensible with money/cars, her last car was kept for 8 years, so I recon it wouldn't be till 2022 she gets bored of the Lexus!!
