Saab 9-3 EZ 2003-2005 Buy Lim. Convertible at all?

Hello, my Opel dealer on site offers me: Saab 9-3 1.8 t Cabrio Linear 150 hp, 50,000 km, EZ 11/2003 or Saab 9-3 1.8 t Limousine Linear 150 hp, 70,000 km, EZ 9/2003. Cabrio was never a topic for me, alone because of the payload – because Saab is quite strong in the convertible area (for Saab conditions), how is that in practice, is the payload sufficient for you? A familiar rides a VW Beetle, since you can not even invite a box of water when the cover is closed. I had a Saab petrol engine (small engine), but the dealer said these engines would be older from the EZ. The price for both cars is relative for me, for me it’s more about me – can I even say “JA” to Saab? The Saab 93 is built on the platform of the Opel Vectra, but with only the Saab is better – but if the quality is not right then I prefer to leave it. My dealer was negative in practice, it’s a bit earlier. I also showed a Saab 93 convertible that had white rear lights (was already a facelift) the station wagon looked like that, I didn’t like it. If I now concentrate on the predecessor model, which year of construction comes into question and is the change to the Saab at all “usable”? Thank you JD
