Z3s do live OK outside (only kept mine for 5 months though - found the 1.9 too soft).
My 4/4 has lived in the garage since soon after its purchase. No bikes any more (sold the Triumph in Dec 09).

Enjoy the ride when your mate collects his car - as said above, I think you'll be converted too! thumbs

Cheers,
