passie wrotei sold my SP5 last year for 12.5K € but i looks like prices are going up this year so maybe i should have wait... stil have my Strada.
Prices for the 851 and 88 are rising, but I do think that the SP3 will be more of a collectors item than the 888SP's (except for the 888SPS that is...). I do really fancy a nice SP5, and 12.5K for a nice SP5 is a bargain.
