According to an article in the Daily Mail newspaper (UK), Jay has recently bought a Porsche 356 - a classic sports car from the 1950's and 60's.  The part of the article about Jay is as follows:

The best example of an original Porsche 356 has just been bought by fellow car nut Jay Kay.I know this because he took great joy in leaving a message on my phone (we often call each other drunk in the middle of the night while surfing Argentinian car sites) telling me he'd been shopping and bought two mint 356s, one of them the first Porsche ever registered in the UK.It's a bit like Top Trumps with Jay and me.We'll go fishing on his lake and if he catches two I've got to get three. The day after he'd bought his pair of 356s I rushed out to look at an original Ford GT40 he'd told me about, which I might have to add to my collection.
