frankie,
i'm still in two minds about the hard top,if one came up at the right price in atlanta blue I would probably pull the trigger on it and buy....however...
I am pretty sure it would spend 99% of its time in the garage as I think buying a convertible is about having the freedom to go topless when the mood takes you..even in the british winter I have still had the hood down on several occasions,last time being today when I went out for a B road blast around the surrey and west sussex countryside...smile factor 10 captain!...
and driving down empty roads on the way back from london at gone midnight with a warm coat on, under clear skies is one of the most enjoyable driving experiences I have had..a hard top would just take the spontaneity out of it completely...provided your heating/aircon works well and the hood has no leaks I think it is almost superfluous for a Z3..thats what I have found, even in the really cold wet windy weather we are currently enduring in the UK.
my attraction to the idea is more to do with that "bloke thing" of having all the kit for your car, I have even considered buying another Z3 in atlanta with a hardtop and dismantling it so as I have spare body panels and various bits and selling all the parts I don't want or need on ebay to recover the initial spend...when you consider I have seen 2 Zs in atlanta blue recently with hardtops for under 2k...this means walking in the door and handing over £1500-1700 ...the engine,gearbox, wheels, door mirrors,seats,dash and suspension would get me that money back leaving me with a hardtop and a complete set of body panels bonnet etc,a hood and various other components for a minimal spend, when you consider a good hardtop with fitting kit would run me around £800 buying a donor car is the most sensible way to go and would "future proof" my little 1.9 against almost all possible mishaps..
maybe something to consider?
