Ha ha ha, made me think about a photograph I saw some time ago where you could fit 2 Smart cars into a standard parking space, you do realise that the Smart car has one thing the ISF doesn't....... a turbocharger! Having said that the egines are under 1000cc.
You could always put a sticker on the rear end "MY OTHER CAR IS A LEXUS ISF"
I just hope they do an excellent job on your ISF and it was worth all the pain and suffering :)
