I've had 3 Porsche,
2 Cabs and 1 coupe, so I'm more than happy with Cabs.
At risk of being told I'm talking out of my @rse, I question all the people who say that a coupe is stiffer and noticeably so.
I'm sure that technicallly it is, but unless you're driving at over 80% of the cars potential I don't think you'll even notice it, I didn't, and that included trips across Europe, and laps of the 'Ring at a 'modest' speed fair enough.
If a Porsche cab is such a no-no why is there a premium on the price when purchased from new?
I suppose you have to ask yourself where do you live, where do you daily drive and what do you want out of it.
if your commuting into a city every day possibly not, but don't diss a cab just cos of that, that just means it's not practical for your needs.
I loved my cabs, a 964 and 996, what I think puts some people off is the lines of the car with the soft top up, but when you put it down they're beautiful cars, and head turners !!!
Oh, and a bit more talking out of my @rse I suspect, if you're buying a car, any car as an investment, don't.
Even 993 and 964 RS and other previously Highly sought after and exceedingly highly priced, owners are struggling to achieve the prices the owners think they're worth.
buy it cos you want it and like it IMO. you'll never make money on it for sure, whatever it is.
